Dexter Electric Brake Wiring Sierra 33 RLIK

Looking for help for the brake wiring connection layout. Had a blowout and it pulled several wires loose from connectors. It is all located on the back driver side axle. Have 2 wires loose and not sure if I have one missing. Believe one was pulled out of the 3m scotchlock other (black)pulled from wire lock. If could provide picture, hand drawing or other would be appreciated. I don't have another trailer close by that i could look at. Thanks for any feedback

Trailer brake wire should be Blue. Some systems also use a ground which is typically White on trailers. Both are easy to trace. Got children handy? Good bonding experience finding wires under a trailer.

Yep need to splice them back together. The electric brakes run on 2 wires, call it supply and return. On the drivers side you'll have a spot where 3 supply wires come under one wirenut, one from the RH wheel, one from the LH wheel, one from the front of the TT. Same with the "return" wire. Just visualize supply to the brake and return from the brake.

Do yourself a huge favor and just do homeruns for each individual brake up to the front and connect them in a junction box. That is what I will be doing when the time comes. Way easier to troubleshoot too since you can separate all of them to measure resistance of each magnet.

I use something like this for all my trailers.

Some come with the 7 pin harness as well https://www.amazon.com/Primelux-7-Wa...8216329&sr=8-2
