hook up without brake controller
I completed my install without a brake contoller, I hooked up the trailer and everything is fine. I bought the universal wiring kit with the Black box, I cut the ends and put on the flat prong connectors and plugged them right into the mazda connector, I only used the running lights, left blink, right blink, and brakes. In the factory connector they are all separate. I am still not sure what the others are for someone said 12v aux, But i never got power out of the other 2.
Very simple to do, Cost about $20 for the wiring kit, from any auto parts store. And a simple test light completes the job.
I dont need the brake controller so did not look into it...
