How to Install the Dexter Electric Trailer Brake Kit

Speaker 1: Today we'll be taking a look at, and showing you how to install, the 10 inch Dexter Electric Trailer Brakes. They're available for the driver's side and the passenger side, or as a kit with both. They come in weight ratings of 3,000 pounds, 3,500 pounds, or 4,400 pounds. That's going to depend on which axle you have on your trailer.One of our customers, Paul, wrote in, "What is the difference between the 3,500 and 4,400 assembly and how do I know which axle I have on my trailer" Well that's easy, Paul. There should be a tag or information stamped into the axle. You just want to see what you have there, and refer to our site to get the appropriate one. see more >     



I’m upgrading my utility trailer to add electric brakes. I have the dexter 3500 axle with electric brakes. My question is if y’all have a video that fully shows how to wire in new electric brake wiring. I’ve only seen on where it shows the wires lead back to the driver side then get zip tied to the axle and it shows scotch connectors to the passenger side but doesn’t show how the driver side brake assemble is wired to the main brake wiring. It skips to cutting the white wire and grounding it to the trailer frame.

We don't have a full video that shows wiring up the trailer from scratch, but we do have a helpful article that may offer some guidance. I've liked it below. The brake output wiring basically just gets run up to the brake output pin on the trailer's 7-Way.
