Re: 2003 Silverado vs. trailer brake light
since the vehicle came with the trailer wiring the junction block that accepts this trailer plug as I explained previously, you have yet to locate.


remove the spare tire , and follow the wires from the trailer plug. only 2-3ft of wire to this block , remove covering and probe for voltage loss with the trailer lights hooked up.
