I got the the led indicator to light. My + brake light wire needed to be hooked up to constant power. I hooked it up to the battery to test it and it worked. Now I need to figure out where + power from brake switch would be. There is none at the front brake.
Brake light fuse, on the feed out not the feed in
Technically its all the same power source so you could leave it on the battery but I am thinking they have it on the output to the brake circuit to monitor bake lights are working thus signal to the cruise
