Got an '03 GMC 1500HD with heated power mirrors, but no signals. Installed the '06-up camper mirrors, but I need to be able to wire in the heat and signal. Do I reuse the plugs off my old mirrors so I can plug into the door for the heat and power adjustments and then tie into the turn signal wire under the dash? I tried searching on this and found very limited info... Any help would be greatly appreciated!

 

Should be just plug and play on 03 and up. Did you test them out yet?

 

Plugged them in....now none of my switches work on my driver door and my a/c won't come on either... The signal works on the PS though! lol

 

Oh sh*t, I should have read closer. They changed the mirrors in 06 so if you're putting 06 mirrors on an 03, you'll probably have to make a custom wire harness to get everything working properly. I hope you get it done without much trouble
