I have a trailer wiring issue. I suspected my trailer harness to be the problem since it's so typical but after hooking to another tow vehicle they worked fine.
The Chevy dealer took a look at it while I was having something else serviced. I know him pretty well so he was going to handle a quick fix on it without charge if it was simple. He said there was a short somewhere in the system which would've required more work.
My question is, can I somehow tap into the wiring from inside the vehicle and just have a separate plug in the cargo area of the Trailblazer to hook into, thus avoiding the supplied plug socket and hopefully getting around whatever short/ground issue there is?
