Wiring Electric Brakes

[buckeye]

I want to rewire my electric brakes for my trailer. I have removed the wheel to change the bearing, and know notice that instead of blowing fuses, the magnet does not work when I step on the brake or use the electric brake module manually.


I was wondering if all I need to do is run a wire from the 7 way connect on my truck (the one for the electric brakes) to the brakes and bring the other wire back to my truck (to the negative). Is there something else that has to be done? Unfortunately I can not trace the wires once they enter the trailer and I can not determine if the wire does anything else when it enters the trailer.


Thanks.

The belly skin must be dropped to access the brake wiring.

Running a new wire outside the belly skin is NOT recommended as it would leave the wiring unprotected against road & campground hazards.

Your magnet may be bad. Disconnect it, and check its resistance with an ohm meter. The resistance should be 3-4 ohms. Check the wiring for chafing where it exits the belly skin near the wheel.

I ran a jumper wire from my truck to the brakes. And brakes work perfect now. I think I my like you say run a new wire, but thru the trailer not to have it exposed. Wire is old brittle, insulation around wire cracks when I move it with my hand.


I was just making sure when I run a new wire I wasn't missing anything, like an extra wire I can't see.
