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?
have the same problem?
