Re: EB Electric Mirror Conversion onto EA?
the square 4 pin plug is EA-ED. (one pin missing..ie the above photo, one on left...???? the one on the right is EA-ED)
A little investigating may be required. As your car is a fairmont i am surprised that it has manual mirrors.
Having worked on literally hundreds of EA-ED, one thing i have found is that some times all the factory wiring is in place for electric mirrors, but the car winds up as a GL and doesn't get them. For example my EB-1 is a GL with manual, but the wiring is all in place....go figure.
The best thing you can do, is to check inside your doors for the wiring, if its not there, then go to a self serve wrecker and get the factory wiring and fittings. Beware tho, this may be a dash out job, but it is the only way i would go....even dash out.
