Tow a trailer with either a 7-way or 4-way plug with this dual vehicle-end connector. Included pigtail harness hardwires into your vehicle and the connector end mates with the 7-pole socket to form a weathertight seal.by: WillyGDocVT02/11/2024
Quality is good, but wire colors aren’t standard and there were no instructions in the package for how to wire. I had to google standard pin outs and colors. Pigtail is too short, by about 2 feet and I had to splice twice to make it reach the inside of my vehicle (GMC SAVANA). Once I did all that it worked perfectly but what should have been a 1 hour job turned into an all day project. Do not recommend. Go to your nearest RV store.

The service provided by George and Lacey was the best part of this transaction. Lacey helped me find the right parts and sent me a video about installation. They both worked to correct my order and customized the delivery date.
The parts were precisely what I needed to get power to the bumper for a small trailer and bike rack. A few comments: order more butt connectors as the mfr sent 6 and there were seven wires on my Colorado. When connecting the tail harness to the truck harness, be sure all the wires on each side are the same length. The yellow wire strippers take some getting used to, so practice on several wires first. I’m an ‘average’ handy person so these last two suggestions didn’t come naturally to me, but overall this was a pretty simple installation. When I tested it and all the lights worked, I was a happy camper.

Steve, the 6 connectors are correct. The ring connector that attaches to the ground wire is the 7th connector.

2012 Dodge Ram Pickup
This is a fantastic quality part and an excellent alternative to Ford's OE connector (the difference being this one is far less expensive and does not have the Ford emblem. I used the connector to replace the 7-Pin/4-Pin combination plug on my 2002 Ford Super Duty after swapping the bed/bumper/tailgate from a 2012 Super Duty. It is a vastly superior connector in that the 4-Pin is integrally wired with the 7-Pin as opposed to having the 4-Pin spliced into the harness. I would definitely recommend this part for any towing rig. I eve put one on my father's 1995 Dodge Ram 2500. Don't hesitate to order this one!

I have a 2017 SantaFe I have 2 different trailers and need both types of plugs I am using this product along with a curt class III hitch and a curt 56332 wiring harness.
I want the finished outlet to be behind the factory cover I had to modify the Hopkins bracket by bending it in the opposite direction on a angle because the hitch is in the way .a little effort and its great

The trailer plug went bad on my 92 F150 several years ago. This plug is the same as my 10 F350. I like the combination 7 spade/4 pin. Other combos have a rubber flap to cover the 4 pin plug. I doubt I’m that disciplined and I would think that rubber cover would dry rot and break off. This plug has spring closure doors and looks great!

Great product!
Fits the factory hole in the bumper perfectly.
Attaching the wires was a pain but that was due to GM saving $1 by just cutting the wire ends and not installing a plug......but they were all there so that was a plus.
If you do install this setup AND you install a hitch, leave the spare tire down while you attach the wires. There's plenty of wire with the plug but the factory wires are up kinda close to the underside of the bed so not a lotta room.
ALSO spend the extra couple dollars and get the heat shrink butt connectors, they're available here in whatever size you need.
Another thing to think about, if you plan on eventually installing bed/ cargo lights any time soon, now is the time to add that extra power wire before you crimp, shrink, and tape the hot wire......

Bought this trailer connector to use instead of the flat 4 wire connector. Wanted a nice finished look on the rear of the vehicle without any hanging wires. Mounts to the Draw Tite mounting bracket without any modification. Only minor problem I had was with the wiring. The wire colors are not the same between the 4 and 7 pole connector. A call to etrailer got the problem resolved. Great customer service!
by: Jordan A04/06/2019
This is the same look as a factory install. I was greatly pleased with the overall installation. Super easy to wire up and looks great in the bumper. My truck has the clean factory look for way less than what they had quoted for an install.

This item came relatively quickly (with a slight delay due to a backorder, but E-Trailer communicated this very well). The directions, the fit and the on-live install video is very helpful. Please watch the video to be sure you are getting the wires crossed correctly - the wire colors from the harness and the factory wires do not all match so be careful there. Highly recommend this product.

This is a great affordable option to replace your worn out or damaged OEM trailer recepticle. The fit is perfect. It is made by Pollak which is the same as the Ford one you replace. I damaged mine and took the pin connectors out of new housing and installed it on my F350 without splicing wires. Worked perfectly.
by: Jeffrey05/02/2020
I’m glad I chose this over a single plug! No matter what you have on the hitch, you’ll have the plug for it. The pigtail is plenty long enough and the bracket makes for a simple installation. Get some shrink tube or shrink wrap butt connectors as the ones included aren’t going to keep weather out for long.

This, combined with Item #e45ZR and Item #C68JR, worked great to add both a 4 way and a 7 way harness to my 2021 Kia Telluride. I only used the harness from the Item #C68JR kit, not the socket. I replaced the socket with this item.
by: Morris04/16/2020
Perfect connector for what I was looking for on my 2019 RAV4. I originally installed it with the L bracket, but later changed it to be flush in the bumper. Looks very clean. The prefab pigtail made install into the car very easy as well.

Only gripe, the plug wiring on the back is at a 45° and the plug in on the front is at a 90°, so dont wire up the wires by the wiring plug but how the plug in on the front would plug in, I made the mistake, but other than that, works great, looks great, fixes botched wiring like my truck had with just twisted together and taped up wires, easy install
by: Garet02/23/2018

Bracket is most likely 14 gauge (measured it) and should be easy to weld. Connector appears to be of reasonable quality, but time will tell if it holds up or not. No matter, welding the bracket to my rollpan will be the difficult part, not replacing the connector housing, should it fail. Hard to rate something I haven't used, so first impressions, I guess it's a five star.

Nice upgrade in place of 4-wire-only. Looks good, works good.

by: Brad J05/03/2023
easily connected. liked direct wire system. however lights worked at first, now all are out but brake lights. I think this may be due to the connectors used. havent had time to trouble shoot it yet.
by: Thomas 04/08/2023
Same as the trailer receiver easy and simple to install following the installation video. I did use the heat shrink butt connectors as suggested in the video, keeping the connections as much as possible corrosion free.

- Is the 7- and 4-Pole Trailer Connector Socket a Fit for Ford TrucksThe 7-Pole and 4-Pole Trailer Connector Sockets w/ Mounting Bracket and Wiring # HM40975-11998 is a hard wire application, as you can see in the linked installation video we made of this being put on a 2008 Ford F-250. If you only need to connect the plug, which is 7- and 4-Pole Trailer Connector Socket # HM40975, that is a direct replacement for many different years, makes and models of Ford trucks with a factory 7-way; for example it is a fit for a 2018 Ford F-150.

For only the pigtail side of the 7-Pole and 4-Pole Trailer Connector Sockets w/ Mounting Bracket and Wiring # HM40975-11998 you just need the Pollak 4' Pigtail Wiring Harness # PK11998.

The pigtail would wire up according the description shown on its product page, which you can see by clicking the provided link.

For a 4-Way you can use # 118315. Then you would use 4- and 7-Way installation kit # ETBC7. This provides a 4/7-Way connector using the previously installed 4-Way for the light functions and also includes the wiring for the 12 volt circuit, reverse lights (if needed) and brake output.

- Fit and Compatibility of 7 Way Trailer Plug on a 2006 Toyota Tacoma TRD Access Cab 4XGood news! I can help you find the right 7-way connector for your 2006 Toyota Tacoma. If you have a plug similar to the one I have linked to this page for you, and it isn't damaged too then I recommend the # PK11893. If your factory plug is hardwired directly to the 7-way, then I recommend the # HM40975-11998, this will give you a plug, just in case the 7-way plug were to get damaged again. With this harness you will just want to match function to function and splice the wires to match...

- Does a 7-Way Need to be Installed on a Second Trailer When Double TowingTechnically you don't "have" to have a 7-Way, but if you will be towing your utility trailer with your tow vehicle only sometimes then a 7-Way is the best way to go. Using the Epicord 7-Way Molded Trailer Plug with Junction Box # 277-000141 is an option to do this. The junction box is labeled on the inside which makes your wiring much easier. If you are only wanting to add the braking function then you will need a minimum of 10 Gauge Wire # 10-1-1 to run from the junction box to your...

Then you can use the 4 and 7-Way installation kit, # ETBC7, which comes with everything you will need to maintain the 4-Way and add a 7-Way. It also includes components to hardwire in a brake controller. Adding a 4-Way first makes it easier to install the 7-Way so that is the main reason you would install it first.

You can use any 5th wheel/gooseneck wiring harness with the same type of connectors that plugs in line with a 7-Way. I recommend # 50-97-410. It has the 90 degree bend at the back of its 7-Way which is easier to fit inside the walls of the truck bed on your 2000 Ford F-550. I have linked a video...

- Parts Needed to Make 7-way Euro to 4-Way AdapterI do have an option for you but they do not offer an adapter to go directly from a US 4-Way to a Euro 7-Way. However, you can make one of your own using only the part # 118158, part # 16-4B-1 (per foot), and part # HM48192. I have then attached a wiring diagram on this process for you. You'll have to source the correct trailer connector style local to you as we don't have a Euro style 7-way.

- Trailer Wiring for 2004 Chevy Silverado Without HitchFor your 2004 Silverado, the Replacement Custom Multi-Tow 7-Way and 4-Way Trailer Connectors # 30955 will work with your stock wiring harness if you have the tow package. If you don't have the tow package wiring then you will need to go deeper because the standard wiring had the brake light and blinkers on separate wires so a converter is needed.

- Troubleshooting Trailer Brake Lights with 2001 Chevy Silverado 3500You can test your Silverado's trailer connector, without a trailer hooked up, using a circuit tester like # PTW2992 or # PTW2993.

You can also test the trailer on its own by applying 12V power directly to the various circuit pins on the 7-way plug. The linked photos show you which pins carry which signals, for both the truck and trailer 7-way type of wiring. Since the trailer brake...

- Solution for Going From Euro Trailer Wiring Connector to RV 7-WayThe best solution I can offer you is to cut the Euro 7-way off of your vehicle and wire a new 7-way to your vehicle by function. The best way to do that is to use a circuit tester like our # PTW2993 to determine the functions of the wires by having a buddy apply the different brake and tail light functions while you use the # 3808 to determine which wire does what and then wire it to the 7-way like the picture I attached. Once you do this you will be able to tow your boat trailer, but...

It also comes with the fuses and relays to make the 7-Way functional. Instead of using the 7-Way only that is included though you would want to add # HM40975 like you said.

- Does Trailer Coupler Need to be Attached to Trailer Hitch to Properly Test Rear Signal LightsThe trailer does not need to be physically attached to your vehicle's trailer hitch to properly test its rear signal lights. As long as all the wiring is correct and connected between the tow vehicle and trailer, everything will test just fine without actually attaching the trailer coupler. In fact, it is better to test the trailer lights with the trailer uncoupled, so you do not experience a false ground.

For Hopkins wiring they follow the following wiring scheme: Red = Left turn and stop White = Ground Blue = Electric brakes Green = Right turn and stop Black = Battery Brown = Running lights Yellow = Reverse lights. If you need to add additional wire we do carry jacketed 7 wire by the foot as part # DW04914-1.
