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.

Works good, easy to get all the wires to and to the plug. I would like to see them use better cover bolts, so they don't rust. 767509
Quality part. Makes wiring and troubleshooting a trailers electrical easy. 608194
Easy to install, nice that posts are color coded but not necessary. Great to have blank plugs and 7 way loom size grommets. 677700

Used this product to upgrade both of my trailers. Makes troubleshooting the wiring harness very easy. 711349
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 off....so the whole thing is a useless waste of time and money! 569119
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
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
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
Products as advertised. Prompt shipping. Thanks 678448
Great product and price 825289
Quick delivery. Sale price was great! Paid less for 2 units then I would have paid for a single unit locally. 819864
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. 819566
Exactly as advertised 816381
Great product for adding options to any trailer. I used it on a boat trailer I was putting new lights on that had integrated backup lights. 812259
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!” 808578
Good product fast shipping 806230
The products are exactly what I needed. Delivery was in a couple of days from placing my order. 802551
Meh. Bought this thinking it would be made for trailer brake connections, but blue terminal is labled aux. Probably doesnt matter, but colors dont match the harness cable. :( 802394
Really nice junction box. Perhaps over the top for a 4 wire utility trailer, now it will be easy to replace the box to tongue wire a harness. 787073
thumbs up 786641
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 776294
