It’s easy, just connect one end to the brake light + wire and one end to a ground wire or the chassis, and mount them away from the wiring because they get hot. I installed mine in the area behind the tail lights.Ok, gotcha. That makes sense. I was just thinking and picturing things in my head from when they went in. I've got my resistors off Amazon so i'm ready to do it, just need to find a time when it isn't going to rain to crack things open and do the needful.
I'm wanting to install a rear view camera and a steering wheel controls module and i'm thinking maybe it would be good to get all that work done at the same time. But maybe i'll just do the lights/cruise control first since it doesn't seem hard lol.
