Speaker 1: Today we're taking a look at a trailer wiring junction box. This is a durable ABS plastic box that creates a fast, easy way to connect the wires from your trailer connector to the wiring on the trailer for either a six way or a seven way connector. It also makes replacing your trailer's connector simple if and when needed. The electrical junction box consolidates all the wiring connections on your trailer to one location.It mounts to a secure area of the trailer's frame. As you can see, internally it features seven terminals or posts. Each post comes with a flat washer and a nut.It's really simple and easy to use also, and I want to point out that the terminals are all color coded which helps you stay organized.It comes with hardware to secure the lid to the box so that has two holes right here so that way you can attach the lid securely.It also comes with the internal strain relief brackets and screws.It comes with rubber plugs already installed which keeps dirt, grime and moisture out of the box.
Then for whatever slots you want to use, you can remove the solid rubber plug and replace it with a rubber plug that has a hole in it for the wiring to pass through.Now basically how you would use this is you would put ring terminals on the ends of all your wiring on the trailer side and on the trailer connector side. If you have a yellow wire from your trailer connector, you put a ring terminal on it, connect it to the yellow post. Then if you have a yellow wire from the trailer side, put a ring terminal on it, connect it to the same post and then that combines those functions together. Then you just repeat that for all the different terminals or connection posts.I want to go over a few measurements with you real quick, starting with the overall measurement going edge to edge in this direction from outside edge of one tab to the same point on the other, it's about eight inches.Our mount holes are separated on center by about 7-5/16" as inaudible 00:02:17 going in this direction here at the base is about 3-1/4" and the overall height or thickness gives us a measurement of about, I would say, about 2-1/4" to 2-3/8" right in that area.That's going to do it for today's look at the trailer wiring junction box.

It will make the wiring replacement/upgrade for my dump trailer easy.
Mark F - 01/23/2021I 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
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!”
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!
I have bought 2 of these, they make wiring my trailers very easy. It makes for a very sanitary looking job.
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.
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.!.
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.
Used this on my 5th wheel and has worked very well.
Easy to use and solved Ford 7 wire convention verses harness I had.
I have been building trailers for a while now. When I found etrailer they cut my cost way down. I really haven’t shopped elsewhere sense!
Excellent customer service and shipping. Product exactly fits my need to connect two tail lights for an extended e-bike rack. The cable and connection box were well built and easy to implement.
A quality product and easy to install
This terminal strip is larger and better than I expected. It will really make my wiring connections easy!
This product is exactly what I ordered. Delivery was fast and I’m very pleased with etrailer.
Keeps the connections dry & out of the weather. Quick delivery! etrailer is my go-to place for my trailer related supplies
Works great on the trailer to change plugs when someone borrows the trailer! Great way to wire multiple sockets on the vehicle!
This enclosure is great to terminate the power and also connect the stop, running and license plate lights on my welding trailer. It is waterproof and is "the best thing since sliced bread". Highly recommended
This junction box was really easy to work with. It's sort of not actually necessary, but it makes life a whole lot easier, and I really like the idea of having it for future upgrades and changes. Build quality was great and I'm just plain glad I bought it.
These are the only way to wire a trailer. From bumper pulls to goosenecks, so easy to isolate any problems.
Product was used on my 25 year old horse trailer to clean up all the splices and additions that has occurred over many years. Color coded terminals was a bonus.
Just the right size for my trailer, great people Thank you!
Great little box and gets the job done
