Speaker 1: Today we're taking look at a trailer wiring junction box. This is a durable polypropylene box that creates a fast, easy way to connect the wires from the trailer connector to the trailer wiring 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. It mounts to a secure area on the trailer frame. Number of terminals that this one has is seven. Comes with a flat washer and nut for each post.Basically the way that you would connect your wires to the post is you would take the wire from the trailer plug, strip it back a little bit, put a ring terminal on it.
And then take the corresponding wire on the trailer, put a ring terminal on it and connect to the same post. And you'd do that for each function.It comes with the hardware kit. So in this bag is the hardware to secure the lid to the box. Also there is strain relief brackets and screws. And it has the rubber plugs.
So you have one, two, three, four, five different access areas for your wiring to feed into. Now some people, what they like to do is remove the plug completely and just have the area for the wiring to be able to pass through into the box. What I recommend doing to keep the elements out - dirt, grime, and moisture - is just to cut an area in the plug itself for the wiring to pass through.And then it has your strain relief brackets and the actual mounting areas for the strain relief brackets. What that does is that puts tension on the wiring that's passing through and reduces any type of stress or strain placed on the actual wiring. So it's nice that those are already included.We'll go over the measurements real quick.
So taking a look at the overall measurements, going edge to edge, mounting area to mounting area. This direction measures about 8 and 1/2 inches. Side to side, going this direction, is about 3 and 5/8 inches. The overall height is about 2 and 1/2 inches. The mount holes on the unit, these mounting tabs right here, these are separated on center by seven and 13/16 inches.That's going to do it for today's look at the trailer wiring junction box..

Makes replacing your trailer's connector simple.Nice junction box. Used this as a junction/access point for my ‘18 Equinox flat tow setup. It houses my 5way conductors for tail lights, the Roadmaster battery charge line circuit breaker and fuse lead to my accessory +12v port that I’ll plug my Brake system into. Also added a cut off toggle switch on the charge line when not in use. 764663
I chose this box because it was economical and I didn't need it to be water-tight because I mounted it inside my old camper. My priority was to organize a mess of wiring and to make it simple to switch the type of tow-vehicle connector. I'm very happy with the result. Those little nuts that fit on the terminal posts are 3/8 inch - so get a socket that size to help you screw them on and off (with your fingers not a wrench). And be prepared for those nuts to fall down and roll into hard-to-reach places inside the box. If you have a magnetic retrieval tool you can save some frustration. 581695
Just what I was looking for, needed to rewire my Army truck tail lights and this box fits a treat. and is the size that I can hide from the rivet counters. Thanks again and other items I have had from you in the past. 643411
I have used these before and they are great for a trailer wiring project. However, you must be careful when mounting to ensure that you do not crack the housing. If the mounting surface is not perfectly flat and/or the mounting tabs flex it will crack. i mounted two on my trailer and one cracked the other did not. A little silicone will seal it up! 692400
A good way to consolidate and terminate trailer wiring. I mounted it on the front of the trailer in an easy to reach place. Built in cable clamps are a nice feature. 593748
Used this box under my truck to connect both the bumper rv plug, and the fifth wheel rv bed plugs to the truck wiring. Made the job easy!! 678314
This terminal strip box is well designed. It has seven studs with washers and nuts plus a very clever arrangement for getting cables into the box - two on one end and one on each of the other three sides. Each hole has a blank (closed) or holed opening to accept a cable. Pretty clever. The slots in the box fit these plastic grommets and allows either an opening or a covered slot to be used. I mounted the box in a horizontal position on the bulkhead near the battery supply for the breakaway switch. I ran the main 7-wire cable to the bottom and spread it along the studs according to the diagram for the color scheme. I ran the cable from the trailer to the right side (where the two cable entries are located) into the upper access hole and distributed each wire to the appropriate stud. This allows any other application to access the power source such as lighting or other accessories. I used only lights, but I had to connect the power for the lights to the blue wire out of the battery box since it is the only wire with 12 vdc on it all of the time. When the cable is hooked to a vehicle, the 12 vdc connection has 12 vdc, but when it is not connected, the 12 vdc connection is not used and shows only 1.5 vdc. This is the black wire on the battery box. The white wire is ground - between these is the power for the battery charger. The blue wire, however, has 12 vdc on it at all times, so disconnect the battery before hooking it up. And don't connect the blue wire to the blue wire of the cable from the vehicle. The blue wire must be connected to one of the wires on the breakaway switch (I used a red wire to the switch and a black wire back to the box) and the return wire is connected to the blue wire for the brakes. So when the plug is inserted in the breakaway switch, the switch is open and no power applied from the battery to the brake solenoids. When the plug is removed, the switch is actuated and 12 vdc is applied to all of the brake solenoids in parallel. The one side of the switch is hot all of the time unless the battery is disconnected. 652889

Had plenty of room for the wire. 769796
We use this wire for multiple applications and works great at a very low cost. 770105
product as described. fast delivery 756506
Beside using these boxes on trailer tongues, they're also handy at the rear of trucks. Heavy duty trucks also use seven wires. Different plug, round pins. I've used similar boxes to tidy up the wiring on many big vehicles. These seem to be decent quality at a fair price. I got this one to add a trailer connection on a school bus converted to a camper. It was shipped promptly, UPS sat on it for a few days. 746113
