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.

This is my second order for this part. I was pleased with the first one and the quick and efficient service, not to mention the price, I decided to get a second one for my other trailer 577778

This is a piece of crap! Cheap plastic. And the terminals you need for 10ga wire are located at the ends of the terminal block, so you have no space to turn that 10ga wire back on itself to make a proper connection. Then one of the screws for the cable entry/cinch snapped the whole thing is a useless waste of time and money! 569119

Very pleased with this product. 650311

The box is rather light weight for the amount of wiring that has to go into it. The positive and negative posts are together at one end next to the cover attachment post making access very difficult. But the box is better than what the manufacturer provided. If you are adding disc brakes with an additional four wires you might consider a different box. 637992

The terminal box worked perfectly for my rebuild of my trailer from a single axle to tandem axle. Made the plane rewiring of the trailer much easier! 636948

A friend use one of these on a recent trailer project and I was going with one of etrailer’s coiled 7 way cables so I ordered this junction box to connect it. Great construction, simplifies connections for a much more serviceable and neat appearance. Recommending etrailer to all my friends and family. 595636

Do you have a question about this Accessories and Part?

  • Can a Junction Box on a Trailer Short Out?
  • Junction boxes like # 3375601101 have independent terminals for each function that don't connect to each other. It would be very possible for a connection to go bad or lose connection, but it is not normal for an entire junction box with all its functions to go bad. I've attached a trailer wiring diagram to assist. It sounds like you may have lost multiple functions, so I recommend checking your ground connection as that could absolutely impact multiple functions and then check vehicle...

  • How to Complete Electric Brake Wiring to Trailer Connector
  • It sounds like you have a junction box like part # 3375601101 installed on your trailer and the brake output wire from the assemblies are ran to this but not to the trailer connector. If that is the case than all you will need is a ring terminal like part # 44-5310A and some spare wire like part # 10-1-1 to finish running the brake output wire from the junction box to the trailer connector. It sound like you may also need a new trailer connector as well and for that I recommend the...

  • Is the Yellow Wire For the Reverse Lights On the 7-Way Molded Trailer Wire Connector H20043
  • In regards to the 7-Way Molded Trailer Wire Connector part # H20043, the yellow wire is for the reverse light circuit yes. This should then align with the pin responsible for the reverse light circuit on your vehicle. The terminology used for "AUX" is the same as the reverse light circuit. Please note, if you are rewiring a trailer I highly recommend you use a junction box, the Trailer Wiring Junction Box part # 3375601101 to keep everything organized.
