What Connector To Use From Main Harness When Installing Electric Brakes On Trailer

Question

Question:

I am going to be installing new brakes on my travel trailer. I will be replacing all the existing wire that runs from brake to brake on each axle. My question is, what is the best wire connector to use for this, where my wires tie into the first set of break where there is 3 wires. The current connectors look like a molded type wire nut. I will be using the weather proof but connector on wire coming off each connection of the magnet tot he wire nut itself. But just not sure what to use where there will be 3 wires coming off the main harness for Hot and ground.

You can still use a heat shrink butt connector like part # DW05745-5 to join the 3 wires coming off the main harness part # H20046 when are installing the brakes on your trailer.

Brake systems are not dependent on the hub bolt pattern. So you can use the Electric Trailer Brake Kit #AKEBRK-7-SA for 12 inch hub/drums or #AKEBRK-35-SA for 10 inch hub/drums. Then use #10-1-1 wire sold by the foot for your brake magnet wiring.…
