Loaded Mirror
IF THE IMAGE IS TOO SMALL, click it.
This now has almost everything modern mirrors have, plus the off-roading lights (which Ford added to new trucks the year after I did this).
3 wires are still being used for the motors.
2 pins are used for all the grounds (to make sure there's enough ground capacity)
1 wire for the turn signal LEDs
1 wire for the flood LEDs
1 wire for the puddle LED
I have not yet attempted to add memory to these mirrors, but I assume it can be done.
I've added heat to a few sets, including a local friend's Bronco.
