Hello, I'm in the process of getting ready to install my GTPHELLO mirrors on my Monte Carlo. (they needed painted to match my Black car) NOW COMES THE ISSUE The Pontiac mirrors are not heated, montes are. The wire connections do not match ( I'm going to replace them with new ones that do) but the GTPHELLO mirrors are electic as min ea re as well. So should I hook up power just to the power from mine and hope they work, I don't want to hook up the heater wire and then I think I'm all set, because the monte has 4 wires and the Pontiac has 3. Does anyone know what wire controls what? Even if I don't get them to be electric, it's no big deal, I have yet to re adjust my mirrors since I bought my Monte, it just would be nice to do so if I wanted. Also, any wire diagram for the 'Zante mirrors as well? Thanks ....look forward to learning,.... MICHAEL...
