Video Transcript for Mighty Cord 7-Way RV-Style Trailer Connector Installation A10-7W10
Speaker 1: Today we'll be having a look at, and showing you how to install the Mighty Cord, 7 way RV style trailer connector. Part number A10-7W8. Now your cord can become damaged in many ways. Most commonly, you forget to unplug it when you uncouple from your fifth wheel trailer or your other type of trailer that you have, and it breaks off or tears. Something of that nature. Or it drags on the ground somehow when you're towing your trailer and it wears holes in the wire.
That's a good situation where you're justified replacing it.Now the replacement cord that we have here today is a molded design. What that means is that our connector is molded onto the cable end to help prevent moisture from getting inside. We have a total length of eight foot of wire to go to our junction box or our unions where our wires will meet the rest of the wiring on our trailer.This is an ideal replacement for broken, damaged, worn out, frayed connectors for your trailer. This will work with fifth wheel trailers, gooseneck trailers. Any trailer out there with a seven way connector, this will work for it.
This seven way connector is available in various different sizes to fit your needs or your application. It's super easy to plug in. Just line up the tab on the top of it, and slide it into your seven way on the back of your vehicle.Here's what it looks like installed in conjunction with a junction box. A junction box makes it easier for you to add replacement lights down the road, or to add additional lights or other features to your vehicle or trailer that can work off of your seven way connector. Now that we've gone over some features of our Mighty Cord seven way connector, we'll show you how to get it installed.
We're going to cut off our existing seven way wire past all the damaged section, making sure we leave enough slack in it to reuse our junction box.You want to make sure that you have your batteries disconnected on your trailer at this time if you have any. This is the junction box we're using. We're going to take our cord, measure a little bit less than the full length of it, and we will cut off the outer sheathing. Okay, once we have it cut all the way through, we can pull back the sheath, exposing our wires inside.Now, we'll open up our junction box. Now inside the junction box, you can see it's labeled with the corresponding colors.
You have your white, your black, your yellow, your red, green, brown and blue and the corresponding functions which are correct in most applications. But because we're just using this to combine our old seven way wiring with the new seven way connector, we'll just match them up by color.Now we'll take one of our grommets that comes with the junction box. Slide our wires through it. Make sure the sheathing goes inside of it. Take our junction box now, take out one of the knock outs, slide the grommet into that hole. Okay, now we'll secure the wire with a clamp and our provided screws and we'll tighten these down so the wire can't be pulled out. On our replacement seven way, I went ahead and cut off some more of the sheathing. I'll slide another one of those grommets over the wires and down onto the sheathing itself. We'll go through another hole and we'll clamp it in place just like we did the other one. Now I'll pull back and make sure it's secure.Now we can start stripping back our wires, cutting them to length, and matching up with the corresponding colors. We'll start with our blue ones first. We'll strip back some insulation from both blue wires and on each blue wire we will attach some small yellow ring terminals which we have available on our website, clamp them in place. Slide them over the stud for our blue terminal. Place on one of our star washers followed by a nut, and we'll tighten that down.We'll continue this process for all of our colored wires, matching them up color to color. All right, with them all secured and matched up properly, we now have a proper electrical connection and if we need to add any accessories later to our trailer such as extra lights, we can easily do it inside of our junction box.With all of our connections made, we'll put the cover on, resecure the screws and now we're going to mount our junction box up next to this other electrical box in our king pin box. We'll be using a couple self tapping screws to secure this. Just like that, with our screws installed, our junction box is secure, and is readily accessible in case you need to make any repairs or add any electrical accessories such as additional lights.Now that we have everything installed, we'll take our new plug and we'll plug it into a seven way in the back of a truck the test out all of our functions to make sure everything is working correctly. Okay, we'll start by turning our headlights on. See our taillight running lights are working properly. Do a left turn signal. That works. Right turn signal. That works. Step on the brakes. Those are working. While we're stepping on the brakes, we'll make sure our turn signals work correctly.That's all good. Everything is working properly. That completes our look at and showing you how to install the Mighty Cord Seven way RV style trailer connector, part number A10-7W8.

Ordered this for my stock trailer. Good quality. Works like it should

Great jack for the money! Much better than the jacks that come on most utility trailers that wear out quickly.

A quality product.

This is a great replacement cord. Put this on a broken one for my 5th wheel and is working great!

Quality products fast shipping so easy
by: Eli07/03/2017
Overall a good product, but it could be better. Two main improvements would help a lot. First, color coding the wires to match industry standard instead of the random coloring that is used. Second, the plug is twisted, see picture.
by: David12/29/2021
Great quality. However, the wire colors do not apply to the proper loads. Brown has always been tail lights for many years but on this plug, it is green. Why are there different colors for 7 pin plugs vs 4 pin? That makes everything extremely confusing. A single standard needs to be adopted.
by: Taha08/20/2017
Have had this for a year now. Use it once a week in summer. Connection is still 100%. Great product.

Its been a year since I got this. The cord has stood the test of time. I dont store it outside so weather isnt the challenge. Its more like the long summer drives. Condition wise it is 98 good, just minor scraps and scratches. No connectivity issue or shorts. I would highly recommend this over others.
by: David 08/15/2023
Looks like a good product, thicker than what I had, will be using it in a few weeks
by: Timothy03/02/2019
So, I have been wiring trailers for a while now. I have been known to wire thing backwards before. So when I got all finished wiring it up and my marker lights were flashing , I thought, I did it again. Re check all the wires. And I have brown for brown, green for green, and yellow for yellow. Well come to find out, nothing is color coded with this pigtail. Cut it all apart and rewire it all. They said they sent me a link for the wiring but I could not find anything about the colors not matching.

There is more than one accepted color code for wiring a 7-way trailer connector. We explain the color code above in the product description.
by: Dean02/27/2018
Cord is good quality but wire color code doesnt follow the normal trailer light standards. It makes more work for you have to I.D each wire back to trailer plug
Mike L.
2/27/2018
The trailer connector you purchased does indeed use a different color code, which is why we specifically mention this on the product page. The connector would wire up as follows- White wire is Ground, Red wire is Left TurnBrake lamp, Brown wire is Right TurnBrake lamp, Green is Taillights, Blue is Trailer Brakes, Black is 12-Volt power from battery and Yellow is an auxiliary circuit, frequently used for the reverse lamps.

by: Daryl03/04/2017
I replaced the hydraulic hitch system with this. We have to replace the hydraulic brake drums with self adjusting electric brake drums which we feel will be a better system based on our load. We are hauling a couple of RZR'S so the weight distribution was a concern. All the parts have been good to work with. The attachment nUt sav and lock washers were not with our package. A phone call later and etrailer had them on their way. The sad part is the Postal service has lost them at the delivery point.
The videos have been helpful in getting us prepared for the upgrade of our trailer.
by: Ronald02/04/2019
Works good no problems. Replacements on company trailers. We have had them on for over a year with out any issues.

it works fine, no problems this year
by: Brian08/15/2020
This was never right from the start. The brake controller portion worked, but I ended up wiring in a four flat for my lights because we were leaving on a trip the next morning. I was busy and never got anything done about it, and eventually replaced the molded plug before I sold the trailer. Hopefully mine was just a fluke.
by: Joe S06/08/2020
Quality of the product was good but wtf. I’ve been wiring trailers and trucks for years. The colors of the wires used to be pretty standard and nothing was standard on this plug. And no diagram so I had to ohm out every pin and wire to fuigure out what went where. I don’t think I’ll buy a molded plug again
by: Dennis06/02/2020
A very well made trailer wiring connector. works like it should. replaced an older plug. easy to wire. like the way the plug and wire are a one piece unit, no place for water or dirt to get in. I am very happy with this connector. thanks.
by: Michael12/29/2019
I often have to fix wiring harness in the field after some idiot managed to forget to unplug when disconnecting a trailer. This allowed for a quick change with out too much cussing. I added loop connectors to the ends ahead of time making the field repairs faster.
by: Don Mc08/03/2017
I wanted a better wiring harness then what the usual discount national auto parts stores stock. So I went to the web and found this site. Ordered the six foot model (I had been having the existing harness disconnect from the four plug adapter too many times) to give me enough length.
Seems very high quality, both the individual wires and the outer protective sheath.
Wiring was pretty simple; slight difference in color coding. Just take your time. I used the 3M heat shrink crimp connections.
Here's a wiring tip:
If you cut the wires in a staggered sequence, instead of all the same length, then when wrapping, you don't end up with a huge bulge where all the crimped connectors are.

- Would Mighty Cord 7-Way RV-Style Trailer Connector # A10-7W6 Fit 7-Way of 2016 Chevy Silverado 3500The standard 7-way trailer connector has not changed at all. The part # A10-7W6 that you referenced would work well with the 7-way you have on your 2016 Chevy Silverado 3500 though. It's possible your old connector or the truck's connector have corrosion or bent pins which would need to be cleaned/straightened.
view full answer... - How To Install Mighty Cord 7-Way RV-Style Trailer Connector With Different Color Tail Light WiresIn regards to the Mighty Cord 7-Way RV-Style Trailer Connector part # A10-7W6, the most common mistake people make is that they try to match colors for installation which you just can't do. The trailer connector has seven wires, each of which with a certain function. Odds are, the tail lights you are trying to install have different color wires so you need to match function to function, not color to color. I have attached a list of each function for the above trailer connector below. Yellow:...
view full answer... - Recommended Trailer Wiring For 1995 Ranger 690T Boat TrailerI did some research and found that your boat is 18-ft 9-inches long. You did not say if your trailer has brakes included which will make a difference when installing the wiring. If you do not have brakes on the trailer and you only need wiring for the lights I recommend part # A35W42B. This is a 35-ft long harness and it has a 4-way flat trailer connector included. This is a wishbone harness that means the running light is split at the connector and the brown running light wire is run...
view full answer... - Shouldn't Hopkins Square 6-Way 37995 Come with Thicker Gauge WiringAll of the wires of the Hopkins 6-pole part # 37995 are 18 gauge. I would agree with you though that the ground circuit, brake output, and 12 volt accessory circuit should be a heavier gauge like 12. That's part of why I don't recommend this as a great solution for trailer wiring. Instead I would replace the square connector on the trailer with a standard 7-way like the part # A10-7W6 which comes with appropriately rated wiring for circuits.
view full answer... - How To Wire Third Brake Light for Truck Cap on Chevy Colorado In order to power the third brake light on a truck bed cap you will need the Pacer Performance 3rd Brake Light Logic Module part # PP20-702. The reason you need the module is that the brake/turn signal circuits and trailer lighting circuits are combined so you need to separate the brake/turn signals or else the third brake light would blink when turning. If you didn't want to splice into any wires on the vehicle you could make your own harness with the Mighty Cord 7-Way RV-Style Trailer...
view full answer... - Replacement 7-Way Trailer Side ConnectorWe do have a trailer side 7-way connector that will allow you to connect your trailer to the 7-way on your 2015 Honda Pilot, but the part # 20147 you referenced is a vehicle-side connector and will not hook up to your trailer. What you need instead is the Mighty Cord 7-Way RV-Style Trailer Connector with Molded Cable - Trailer End # A10-7W6. I have added a link to a video review and installation of this connector for you to take a look at.
view full answer... - Electric Brake Compatibility on a Boat TrailerElectric brakes on a boat trailer are able to be used without much issue at all. There obviously is an issue with water and electricity, so it is recommended to disconnect the trailer connection when your trailer is being submerged for launch. A few seconds after pulling out of the water, you can connect your wiring without any issues and have the functioning braking system that is easier to maintain. Many boat trailers are moving to electric systems. I do recommend using dielectric...

- How to Convert a Boat Trailer w/ Surge Brakes to Electric Brakes? To convert your trailer from surge to electric brakes you are going to need a new set of brake assemblies that match the brake flange on your boat trailer. The Dexter Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies - 6,000 lbs item # 23-105-106 have a 5 bolt mounting flange and fit 12" hubs. These would be a great start but you will want to ensure they are the same size as your current brakes. You will need to look inside your hubs as well. If your hubs have casting holes...

Or you can use the Mighty Cord 7-Way RV-Style Trailer Connector w/ Molded Cable - Trailer End - 6' Long # A10-7W6 and in the case of this connector it will be the yellow wire which you connect your reverse light wiring to.

view full answer... - Towing a Trailer with a 5-Way Using a Truck with 4-Way and 7-Way ConnectorsThe easiest way is to use a 7-way to 5-way adapter like part # A75TB. It plugs right in and since you already have all the functions on the 7-way you don't need to make any additional wiring connections. On the trailer side you can add a 7-way like part # A10-7W6. You can either cut off the 5-way and replace it or connect the wires together and have both a 7-way and 5-way to use whichever you need. One final option is to use the 4-way and adapt it using part # 20036. This requires you...

I'm not sure what length you have now but we have the part # A10-7W6 which is 6 feet long, # H20046 which is 8 feet long, and # 54006-059 which is 10 feet long.

view full answer... - Troubleshooting Gooseneck Trailer Wiring Connection with Tow VehicleIt sounds like you have tested your truck with other trailers and your trailer with other trucks and have found the wiring circuits to connect and function correctly. This tends to suggest that there is just an issue between the two specific connectors. 7-way sockets and plugs like # PK11893 that you referenced and # A10-7W6 will vary slightly in their fit with one another so in some cases one or more circuits in the 7-way, such as the trailer brake circuit for example, may not make good...

The Mighty Cord 7-Way RV-Style Trailer Connector w/ Molded Cable - Trailer End - 6' Long, part # A10-7W6, is the same style 7-way cord as the Hopkins 7-Way RV Style Connector w/ Molded Cable and LED Test Lights - Trailer End - 8' Long, part # HM20087, you attached to your question. The main difference, besides length, is the Mighty Cord does not have any LED test lights. Unfortunately, we do not have a Hopkins option that is shorter than 8'....
view full answer... - No Connection to Trailer Brakes But All Wiring is Good & Works on Other TrailerI do have an idea, and since you mentioned your other trailer is working, we can rule out your truck being the issue. Since you mentioned your brakes are new, and your wiring is just fine, the only other thing I can think may be the cause is corrosion in your trailer's 7-way. That's really the only thing that makes sense if the wiring is not damaged, so you will want to take a look and you may see the pins corroded or damaged, and you can replace it with the Mighty Cord 7-Way RV-Style...

If the wires have come loose or the pins inside the connector are corroded, you can replace it using part # HM48190 for 4-way connectors or...

You didn't specify what was severed, but this is the most obvious culprit based on how they connect.

You will simply plug in your current 4-way and then connect the white wire with the ring terminal to your frame bare metal to metal using # FA1131822.

These are self-adjusting driver's-side and passenger's-side electric brakes are 10" x 2-1/4". Brake pads are made of friction material for improved braking and longevity.

I believe the green wire you are referring to carries the right turn/stop lighting functions as you can see from the attached photo of a trailer side 4-Way. The 14 and 16 gauge wires are too small for the amount of power needing to get to the brake assemblies and they could potentially get too hot,...

- Replacement 7-Way and Lead Recommendation for Trailer with Melted WiringSince you have some wiring that melted a 7-way with a plug and lead like the part # A10-7W6 would be a great choice. Or to make the install even easier we have a 7-way with a junction box part # HS381-9000 that you can take your old wiring and connect to a box instead of to lose wiring for a much more secure and easier install. I am not totally sure what you mean by the connection bars but the parts I mentioned are sealed connectors.

Brown is for tail lights on the traditional SAE board, but for this particular wiring, it is green. In this attached help article, it shows the color chart under the RV standard wiring. It is necessary to test each color as it may be completely different on your set up.
