Re: 2000 silverado trailer wiring harness ???

You have to completely make sure that the factory harness was cut, and not the accessory part. GM DID NOT make it so wires had to be spliced. It was meant to be plug and play, it's cheaper to make one harness the same with an extra plug than to make two seperate harnesses. Trace the wires back as far as you can, if they go into a taped up/plastic harness then it was cut, or maybe you'll find the plug. Unplug cut up harness and plug in new.

An example, my truck did not have fog lights when new. I added the GM accesory kit and it just plugged into the existing harness.

Anyway, if you trace the wires back and can't find a plug, then someone stupidly cut it off and you'll have to splice the new plug in.
