Video Transcript for Buyers Products 7 Color Coded Terminal Trailer Wiring Junction Box Review
Hi everyone. Adam with etrailer.com. Today we're going to be taking a look at the Buyers Products seven pole trailer junction box. So this is going to be a really organized way to get all of your wiring from your seven pole of your vehicle tied up to the right function of the wiring of your trailer. This is going to do a couple of things, keep everything organized, keep it all dry because it does have a cap, but also a lot of the times we don't get trailers that configure with the standard seven pole color wiring. Luckily we lucked out and we can do basically color to color, but it's not always the case.
What's nice about this junction box is it is pre colored. Each stud is going to have the color and it does have stated green in text and also what that function will be on the other side.So it gives you a color cue and also a word cue to let you know how to wire this thing up. So when comparing this to some of the other junction boxes we carry at etrailer.com if you're starting from scratch, etrailer does make a kit that comes with a seven pole and a junction box and much more. Also we do have a Pollack brand that comes with a 10 function. So if you have a little bit more use for a couple more terminals here, definitely go ahead and grab one of those.It does look pretty difficult, but honestly it really isn't.
You just got to test your wires. So let's just go ahead and do all that together. So we're going to go ahead and check out our trailer's functions and you can either use a test box or just hook up your vehicle. So what we've got to do is I'm going to grab ground from my white wire here. You can also just ground it to the chassis of your trailer.
With my test box I'm going to be testing the right blinker. Ours is color to color, so brown should be the right one.So you can repeat that same exact process for all the wires. Just remember match it to function, not color. Now that we have all this wiring sorted out and we know every single wire and what it does, now we can go ahead and take our junction box. You kind of want to get an idea of where you want to mount it.
I think I'm going to mount it right here. You want to make sure you can get that cap on and you'll be able to tap in from the sides. Before we do all that, what we're going to do is I'm actually planning on using these two sides here to run our wires in and as you can see there's no holes.So in our kit that comes with the junction box we are going to get replacements that will have holes in them. So since I'm using these, I'm just going to take this out put it back in the box and these are going to eventually seat into the slot there. What I'm going to do to make it a little bit easier on myself. I'm actually going to fish these wires through first. So I'm going to to do the same exact thing for our wiring going to our trailer. Once that's done, I'm actually going to start with the wiring that comes from our vehicle and basically all we got to do is just put it into the slot like so. We're going to have to undo these screws right here. Take that off, put it in there.We might have to avoid these little brown plastic pieces here. That's going to be what's going to secure our lid into place. Then fasten it down. Once you think you're done, give it a good wiggle and make sure it's nice and tight. These ring terminals does not come with the kit. We do sell them here, so if you don't have any in your garage or anything, definitely go and pick those up whenever you grab one of these. Always make sure you've got a good connection and obviously have enough length to meet it to the right function.So I'm just going to put this nut on there pretty loosely just so it's not flopping around. I'm going to go ahead and put some ring terminals on all of our wires. For now I'm just going to match them up color for color on our junction box. So as you can see here, we just finished our vehicle wiring here and we're going to basically do the same exact thing for our trailer wiring. We're going to put this into place, but I got to undo these two screws first. Then we're going to go ahead, put those back, and screw them down evenly.So now we can just go ahead and put some ring terminals on all these wires and we're probably going to have to cut them and strip them back a little bit so they can fit into our junction box. So we've got all of our ring terminals on here and this side over here is going to be all of our trailer wiring. Over here is going to be from our vehicle. What we're going to do is as we put from our vehicle, all these wires have a specific function. So you don't necessarily need to go by the color because a lot of the times these trailer wirings aren't going to be color to color. So you could do it one at a time and test each and make sure that you're matching them up function by function. Let's take this nut off, place it on there.Tuck those wires away a little bit and put that nut back on. We are going to come through here with the tool to tighten these up. So now that everything is hooked up, now's a great time to test everything out and make sure everything's hooked up correctly. We're going to use the test box, but you can also just use your car. All right, so first we're going to start with our taillights.Our left turn signal, our brake lights, and our right turn signals. So now is going to be the time to mount it in its home. I want to angle it like so and we're going to run some cell tappers through this plate. One thing to note these cell tappers are not included with our kit. So once that's secured into place, give it a good wiggle, and make sure it doesn't go nowhere, and then we can go ahead and put our cap on. It doesn't really matter which way because these are going to line up regardless. Then we can take our screws and these we're included with our kit, slide on in there. Use the Phillips head tighten them down. Well everyone that's going to do it for our look at the Buyers Products seven pole trailer junction box.

Color coded terminals in the ABS box provides a fast, easy way to connect the wires from the trailer connector to the wiring for either a 6-way or 7-way connector. Makes replacing your trailer's connector simple.by: David 04/18/2024
This is a nice enclosure whether installing a new 7 way assembly or simply cleaning up and organizing the existing connections between the 7 way harness and the vehicle wiring. Good weatherproofing for installation under the trailer deck.
by: Bill 04/11/2024
I had a problem with my electric brakes occasionally showing a disconnect. Talked to Carol C and she diagnosed and recommended the parts. Uninstalled them and no more problems. Tech support is on point.
by: Leslie08/18/2022
Your connector box is a great product, easy to install each wire by color and number. I had a shorter than I expectd new harness and plug but the box made it eazy to place where I needed it instead of going into the trailer understructure. I placed the box between the traile tung under the battery box for easy future acccess. I hand made a sheet metal shield for extra water proofing.
I reccomend this product, easy peasey.

This replaced an interior metal junction box on exterior front of almost every pull behind camper made. All connections were wire nuts with massive corrosion.
Easy waterpproof fix for a minimal cost.

I have a 2019 Forest River travel trailer. I started having brake problems and the dealer was no help so since i have some experience I started looking at the issue myself. What i found was a series of loose and poor 12v connections throughout the braking system and some in the lights as well. The main culprit was connections in the main junction box, see pictures. The factory used a household style jbox and not a quality sealed jbox. I looked on line to fInd a suitable solution that allowed easy access and easy installation. This product fit the bill Perfectly. After a couple hours work to remove the old box and install the new one (in new location) cut and install proper ends on all the wires and make clean secure connections my trailer now has brakes that work properly. The new box came with all necessary screws, nuts and has plenty of wiring install point options. It is all plastic so i was careful not to over tighten any of the screws used to retain the harnesses on each end of the box.
Thank you for a great product.

Good junction box
by: Andre W.06/05/2020
Excellent product, well made and sturdy.
Color coded anchor bolts to secure your 7pin connections with the wiring of your trailer to match up appropriately with assigned functions from your vehicle’s harness. Which is all standard!
Gasket sealed to help protect connections if attached outside exposed to the elements.
Extra sleeves provided in case your wire harness is slimmer in diameter or wished to seal proof the junction box.
Can’t express enough how easy, convenient, and the quality of this product has been from install and to this point in time.
Over a year in my trailer, and looks just as good as the day I put it in.
It is made of thicker plastic, built to last, and has held up with no deformation of any kind within my enclosed trailer in the Texas heat.
Im sure my trailer, being black, and enclosed, bakes over 160 degrees in there.......if not over or near 200 degrees.
Yet plastic is still good and not brittle, and like I said......is no different than the day I put it in.
I bought it to rewire my whole trailer and to include reverse lights and electric brakes. Original wiring was complete BS and had splicers, which caused intermittent working lights and shorts.
I gutted and rewired the whole thing with thicker gauge wiring, heat shrink connections with heat shrink tubing over that, and any possible friction points I wrapped with tape and put heat shrink tubing over that.
Needless to say, the color coded connections within the junction box made my life so much easier.
Not to mention the thought process that went into the design of this junction box for a clean install no matter where you decide to mount it was a God Sent!
You wont regret this purchase!
I’ll quote Chef Paul Prudhomme on this one,......
“ I Guarantee!”
by: Brandon07/09/2021
This was fantastic for my utility trailer. Made wiring everything super easy! For my small trailer I have led brake lights, side blinkers and I also had a 3rd brake light. There was still room so I put a female trailer plug just long enough to hang out of the box. That way I can connect a 'trailer light tester' and have an idea where potential shorts might be. ;-)

Strong plastic with plenty of room and included grommets to connect new trailer plug to trailer wiring.
by: Jess03/21/2020
This junction worked perfectly! So handy to have under your vehicle to wire up a wide variety of accessories! I used it to wire up flush mount pod lights that I installed in the rear bumper. They serve as reverse lights and they’re also wired to come on with a switch. Very handy!

The Trailer wiring Junction Box has cleaned up the new wiring I installed. I now can go to one spot to check for any wiring problems. It was easy to install and had everything included to protect the wires.

- Recommmended 4-Way Flat Trailer Wiring for Cargo Carrier Light Strip on Travel TrailerMy recommendation for your application is to add a junction box like # 3375601101 which will allow you to connect another wire without "splicing in" on the trailer side and run wiring like # DW03240-1 for a longer run or # 16-4B-1 to the rear of your trailer and then use # HM48190.

For the hitch I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # DT65MR. This hitch will allow you to use a weight distribution hitch, which might not really be needed with a pop-up trailer but we would be helpful later on if you ever sized up. This hitch also won't interfere with the spare tire, as some will require an 18" or smaller spare. To install a 7-way on your Highlander...

Depending on what you will be doing with this wire, the following parts may also be good options for add on parts as well. The Pollak Heavy Duty 4 Pole Round Trailer End # PK11402 would attach to the end of the # RM-1064-B very nicely. This would then pair with the Pollak Heavy Duty 4 Pole Round Vehicle End # PK11404.

view full answer... - Troubleshooting Trailer Brakes Locking Up When Connecting 7-Way To Tow VehicleIt does sound like there is either something not wired correctly or you have a short in the wiring which is causing the trailer brakes to activate and lock up. There is also the possibility of having an issue with the trailer breakaway switch If the pin is missing, broken or damaged internally connecting your vehicle could provide power to the breakaway switch which activates the brakes. I recommend starting by checking the condition of the wiring along the 7-way and also check inside...
view full answer... - Replacement Junction Box for 7-Way Upgrade Junction Box KitI wonder if the box was stressed in some way when bolting it to the trailer. Maybe one of the install bolts was pulled the box in a direction that stressed it. That said, for just the box you'd want the part # 3375601101 which is an exact replacement for what comes with the # HS381-9000.
view full answer... - How To Use Separate Magnetic Tow Lights on Tow Dolly with BrakesIt sounds like you're trying to use two separate trailer connectors together, one for the tow lights like the Flint Hill Goods Magnetic Tow Lights part # FHG96ZR and one for the tow dolly. We don't carry this exact tow dolly so I can't be sure but it sounds like it has electric brakes but no lights and uses a 7-way. The tow dolly lights will then use a 4-way. In order to have both you'd need to combine the two, the tow dolly and tow lights into one trailer connector, a 7-way. I recommend...

The Hopkins # HM20048 you were looking at is going to be 11 feet long, so it's not quite what you're looking for. The longest 7 way trailer side connector we have available is the 18 foot long Bargman # 50-67-106, which will connect to the 7 way connector on your 2007 Toyota Tundra. If you need to, you can make up any distance you need to on your food trailer with either 10 gauge wiring # 10-1-1 or 12 gauge wiring # 12-1-1;...
view full answer... - Replacement Axle, Springs, Wet Bolts, Equalizers, and Brakes for Tandem Axle TrailerI'll start by covering the axle since this information is important for other components as well. The first thing you want to do is identify your axle capacity. Since this is a tandem axle trailer and you're thinking 7,000 lb capacity you probably have tandem 3,500 lb axles. Take a look and see if you have the capacity listed on axle tags. If not, you can measure the diameter of the axle. A typical 3,500 lb axle has a 2-3/8" diameter. If you find that you have a 3,500 lb axle, and your...

- Components Needed to Build a Trailer From Scratch with the Timbren Axle-Less SystemI would be happy to help you put together the components you need to build your own trailer and do my best to keep the weight down. You are off to a good start with the Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange item # ASR1200S04. These weigh around 50 lbs. However, the brakes you linked item # 23-48 are for 7" hubs and we do not have any that will fit the Timbren systems so you will need to go up to 10" hubs and drums. I recommend the Dexter Trailer Hub and...

If you don't already have one on the trailer you can use the Junction Box # 3375601101 and 7-Way Connector # H20046. If you don't already have one on the vehicle we'd need the year, make, and model to inform of options. The seven way would then contain a circuit...

- Connecting New Reverse Lights Wiring At Trailer Electrical Connector For a Dump TrailerAs long as your trailer has a 7-way you will more than likely have a Junction Box # 3375601101 that all the wiring from the 7-way will go into and connect to the trailer wiring. You will need to locate this box and find the wire for the reverse light circuit. This will typically be either the purple wire or yellow wire if your harness does not have a purple wire. A Test Light # PTW2993 can be used to verify that you are connecting to the correct wire. If your trailer uses a 6-way connector...

- How Do The Breakaway Switch And Electric Brakes Connect To A Trailer's 7 WayThere will be two ways of getting your brakes and break away kit connected to the 7 Way plug on your trailer. First will be to simply splice the wires together, but this can be a bit of a pain as you can end up having several wires connected together. The second way, and the much easier way as well, is to use a junction box, like the Buyers Products # 3375601101. This will require you to mount the box and use ring terminals, like the # 44-5310A, to connect everything, but it is the way...

- Parts Needed to Add 10 Electric Brakes on a TrailerIt sounds like you're looking to add electric brakes to your trailer and if that's the case we have everything you need for this. It's going to require hubs/drums, braking assemblies, and some wiring on the trailer. That said, in order to confirm these parts for you we first need to start with your axle capacity. The axle capacity can be found on the axle tag in the center of the beam. The Electric Trailer Brake Kit part # AKEBRK-35-SA for example is designed for 3,500 lb axles and would...

Just be sure you install it in a safe place where it won't get wet since it isn't submersible. The 5' auxiliary wire on the 25 Ft 5-Way Trailer Wiring Harness # A25W5B is usually connected to a surge brake coupler with an electrical reverse lockout which is why it's so short. To...

If you do not already have a junction box, you can pick up the Trailer Wiring Junction Box # 3375601101. Having a junction box makes dealing with the wiring on your trailer easier.

There isn't much room inside of the 7-pole plug so the easiest way to power your jack from the 7-pole would be to wire it to the 12v power in your trailer's junction box. If you follow the 7-way cable along the frame of the trailer you'll see some sort of box where the wires from the cable will run and connect to the wires for your trailer's lighting and brakes.

These have the plugs as well as wire leads that go to your junction box, though if you don't have a junction box you can also get that with part # 3375601101.

This Hopkins connector will be compatible with both the Curt Echo and the 7 way on your truck if you need to tow without the use of the brakes.

Moving on to the brakes, I'm assuming with your 2-3/8" axle that you have 3,500 lb axles. Make sure to verify this information.
