Hi, Bought a trailer with electric trailer brakes. There are 2 wires from the drum. I have the wires and brake controller on my truck located. I know 1 wire from my controller goes to the brakes, but what do I do with the 2nd wire on the brake drum?

Thanks!

Brake magnets are not polarized. Either wire can be positive (connected to the brake controller).

Be aware that some trailers, particularly smaller ones, depend on an electrical connection through the coupler ball for a ground path for the lights. This is a poor approach for brakes; intermittant lights are an annoyance, intermittant brakes are dangerous.

Use a wired return back to the tow vehicle electrical connector ground pin. Don"t depend on a connection to the trailer frame. It"s fine to also connect the trailer frame to the connector ground pin to provide an additional return path for the lights.

Finally, make sure the tow vehicle side is well grounded to the vehicle chassis, or as suggested, run a return wire all the way back to the battery negative connection.

I have run a ground wire clear up to the negative battery cable. Keeping a good ground is sometimes difficult

Trailor brakes work with an electo magnet so one wire goes to the controller and the other one to a good ground. When I work on things like that I ground it in 2 or 3 places because ground love to get lost. I ground to the frame and also run a wire to the ground in the plug in on the truck and I some times even make up another ground that hooks to the truck frame with another plug

Can I ground the ground wire to the trailer or is it better to ground to the truck? As someone said, maybe I should ground to the truck battery?

I ground on the trailor and also at least one wire in the plug that hooks to the truck. Grounds are the most common place to have problems on trailors includeing the light

I agree with Bob. On the Tekonsha and several other brands of controllers Ive had over the years they only run one wire back to the brake magnets and use frame ground as the return. I dont recall they are polarity sensitive?? If theres like a red n black out the drums Id tie the black to frame ground n try her or if black n white Id tie the white to ground.

Let us know

Wires are likely HOT and GROUND.
