Electric Brake Controller

[nhra13]

I have a brake controller I pulled off an 08 Trailblazer and am looking to install it on a 2000 XJ Sport. Is there a write up that shows the wiring for the brake controller? Any help is appreciated.

Wiring for those will be specific for the controller. Was this factory or aftermarket?

It's an aftermarket brake controller I picked up at an even store.

No telling if yours is like the two I have wired in, but they need to be level, have 20A power source on the heavy wire and there should be a ground and one to the brake switch
