I'm looking to upgrade the mirrors on my 04 LB7 to the telescoping arm tow mirrors - my current mirrors are all manual with no signals - I recently had the door panel off fixing the door check and i see no wiring harness inside the door that could support upgrading the mirrors.

Has anyone found a way to do this? I would at minimum like to get the signals working without tapping a wire all the way up to the front of the truck. I had hoped there would be a harness inside as part of a mass production thing but no dice.
