Need mirror / defroster wiring diagram
https://www.f150online.com/forums/me...-scan0005.html
I havent done it yet due to the holiday and Ive been busy. You can do it one of two ways. Either add a switch that sends +12v to the correct wires in the new mirrors or add the 200 dollar heater controls with the factory switch. I hate to say it, but ill probably do the latter because I want it to be right and it to look OEM. Ill update the post when Im finished with the results.
