Asked on May 12, 2011

The brakes on my trailer won't work with the wiring harness on my truck.

I have brake lights on my 2001 GMC Sierra, but I can not get brake lights on my boat trailer. I have a factory installed wiring harness. I have checked the fuses. I have power coming into the brake light switch with the orange wire and power going out through white wire only when brake pedal is depressed. Is this correct?
Thanks,
Terry
