I know this is off topic, but it involves a general electronics topic which is falling silent on other forums i've tried.
I recently bought a car and the previous owner had installed aftermarket side mirrors. They've never worked. I pulled the door skin off today and immediately saw the problem - no connection. Then I saw the factory electric mirror loom has a four pin output, but the mirror only has three pins. And the connection headers are incompatible.
Further poking around and this is factory schematic for the electric mirror:
So i'm trying for a fix. Firstly, does anyone know that the symbols between wire #2 and #3 represent? I'm guessing one on the left could be a switch, but the rectangular symbol is a complete unknown. Google isn't helping me. Can anyone fill me in?
I'm guessing of the three wires in the mirror, one is for X axis, one for Y, and one must be for ground. I'm not entirely sure what's going in the factory loom but there must be some kind of axis flipping going on to get two directions of travel per axis. Schematic also indicates a heating element which I don't intend to use (we don't get freezing temperatures in my area).
Can anyone take an intelligent stab in the dark at a solution? Or is a solution impossible?
Can clarify with more info in the morning after a good sleep
