I have a 2014 GMC Sierra 1500 All Terrain Z71 SLE CCSB 5.3L with the DL3 mirrors (chrome cap, power folding, power adjust, integrated turn signal, puddle lamp, auto dim) and I'm looking to upgrade to the DQS Tow Mirrors. How exactly can I do that and do I need to change my harness or can I use the existing already?
Thanks,
