No that's fine Lol, i found it is the same pin so imagine a motor and you connect live to left pin and negative to the right pin and it spins clockwise for lock. Then you have to reverse the wires to get it to spin anticlockwise for unlock. Problem is that without power there's no live or negative in the control as they float, and there is only 1 connection pin.
So we fit a low power relay which the coil can energise left or right and it closes the switch momentarily to activate the mirrors, however the switch for the mirrors is just a n/o switch and it has no knowledge of whether the mirror is open or closed, so unless you fit some kind of switch that knows if the mirror is in or out and a circuit or something that adds intelligence to the system then all we have is this setup.
If i lock twice they fold shut, if i unlock once they open, that's great, if i lock then open in any other sequence then the mirrors get confused, i then jump in and flip the switch to unfold them.
It works fine tbh and the whole point is so they fold when you park the van and don't come back to broken mirrors so for 1 pound and maybe an hour of careful engineering i think it is fine
You could possibly mount a reed switch and glue a magnet into the mirror so when it folds closed it will give you a basis for controlling when it operates.
