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.
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. ;-)
Very happy with this product. Great for keeping the wiring clean and connections protected. Re-wired a dump trailer. I like to run a ground wire instead of using the trailer framing as ground so my ground stud got overloaded. Ended up installing a seperate ground stud outside this enclosure with a single connection in side this junction box. worked great and has held up well with regular use of the dump trailer.
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. Tim Gunter, TX Happy Camper
Received the Trailer Wiring Junction Box - 7 Color Coded Terminals - ABS. It is well made and includes wire grommets. It will make the wiring replacement/upgrade for my dump trailer easy.
Mark F - 01/23/2021Excellent 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!”
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!
Haven't opened yet but good value and will make rewiring a trailer and finding future electrical issues a lot nicer
Keeps every thing neal organized would like to see bigger box than handle accessories prove access hole weather tighter
works as it should, made the rewiring of my trailer easy. Only giving 4 stars due to being plastic and easy to strip out screw holes.
I have bought 2 of these, they make wiring my trailers very easy. It makes for a very sanitary looking job.
This is a must have for a new build! Makes things simple, and great for existing wiring, get rid of the mess of scotch connectors!
Love them I don't Wire a trailer without using these
This thing is awesome. Even though my trailer was wired one way with the truck wired with different color wires doing different things, with the color coding of this box it made things a lot easier to wire. Multiple ways to get wires into the box, color coded, it made the job of rewiring my trailer a snap.
I put this on a boat trailer to keep the connections out of the water. Easy way to link up the wires and keep it dry. I like the entry points for the wire makes it easy to adjust to different wire sizes.
Works as advertised. I used it on an enclosed snowmobile trailer. When I replaced the pig tail, I decided to replace the existing rats nest of a junction box. The only reason I didn't give it 5 starts is that the plastic isn't the most durable. You have to be careful not to put too much torque on the fasteners. I thought I was using very light torque with hand tools, but I ended up striping one of the fasteners that holds the cover on. I decided to use a light coat of sealant to ensure the cover stays on.
Product was helpful and good quality. Quick service.
Made connecting trailer wiring with truck wiring very easy. The color coding and instructions was very precise and easy to understand. My first time to use a junction box but it won't be my last for wiring a trailer.!.
This box made it easier to check my wiring problems.
Was really looking for a box made in the USA; however, that was only wishful thinking. The boxes worked but I'm skeptical that the box will meet my expectations. More room is needed to adequately attach the wires to the lugs (I used soldered terminal connectors with heat shrink tubing). The replacement grommets that the wire (made in the USA) bundle goes through to enter the box are not tall enough or made to completely seal when the lid is screwed on. Furthermore, the lid will need a bead of silicone as a gasket to hopefully make the box waterproof. I will keep looking for waterproof boxes that can be used for junction boxes.
Great box to organize wiring and make it dummy proof
My husband said this worked perfectly for his project.
Just the right size for my trailer, great people Thank you!
Used this on my 5th wheel and has worked very well.
Good prices, good service and quality p roduct.
Easy to use and solved Ford 7 wire convention verses harness I had.
