Recommended Parts to Rewire an Old Trailer w/ Brakes

Question

Question:

I am wondering if you have any full harness kits for a car trailer. I am buying an old trailer that needs some fixing and would like whole new harness with electric tailer brakes. Please let me know if you offer anything that sounds like this. Thank you Isaac

Hey Isaac! While we don't have one specific all in one kit we do have every component you will need to update your trailer's lighting and brakes.

I recommend using the Trailer Wiring Kit item # ET7WK. This includes a 7-Way connector, a junction box to provide you with a organized and weather proof storage area for all your wiring connections, and all the necessary hardware.

You will then just need additional 16 gauge wiring item # 16-4B-1 for the light circuits and 10 gauge wiring item # 10-1-1 for the brake and 12V power wires, both of which are sold by the foot.

As far as replacement brakes go we have many options. To recommend the correct ones for you I would need to know what size brakes you currently have 10"/12", the capacity of your axles, and the bolt pattern on the back of them. If you could email me or comment below this information I would be happy to find the right set for you.

I have attached a diagram below that will help you get your trailer rewired.
