Well engineered, a royal pain to install

The RZY harness is a well engineered piece but is extremely hard to get installed. Not a fault of the harness at all, it's the way the passenger side of the truck is designed that makes it extremely difficult. The drivers side is relatively easy but the passenger side body harness that goes through to the door area is actually tucked in behind a couple other harnesses, leaving an extremely small spot where it's possible to fish the OE harness down so you can pin the RZY harness in. Then once you do have the new pins in, it's darn near impossible to get the modified harness connector back into it's location and snapped into the body metal. I did finally manage it but honestly if I'd known how hard this was going to be I'd have just skipped the harnesses entirely, installed the mirrors, and called it a day. None of the lighting would have worked but the mirror functionality was the main thing I was after anyway.
