I need serious help! I have a 2009 serria 1500 SL Crew cab with power and heated mirrors. I would like to up grade to ones with turn signals, puddle lights & auto dimming. Would like to also have the power folding option and the "close vehicle sensor" but I think it would take more than just changing the driver door panel. Guess my question is...will my wiring harness accept the full option mirrors? Of course the people selling me the parts say that "of course it will work" but they may just want to make a sale! Any help out there?
