Hello first post. I have my trailer hitch installed on my 02 silverado 1500 & was getting ready to get the trailer wiring setup for trailer lights & noticed that the wire that was tucked under the spare tire had no connectors, just six or so wires w/ the ends taped up. I went to Northern Tool and spoke to one of the "techs" and he said that since there is no plug to connect the wire harness that I would have to get the wiring from the Chevy dealer or just pay a professional to install the trailer wiring. Has anyone else ran across this? Any help is appreciated!
