Numberplate, the associated wiring is from the junction box in the driver's footwell going into the door. The pictures of the connectors on the left are the junction box connectors. The lines leading off to the right represent the wiring going into the drivers door.
When you say you are manually operating the mirrors, I'm assuming that you folded them in before turning off the ignition, after turning off the ignition, you put the switch back to normal, then when you turned the ignition back on, the mirrors come out?
The circuit is already using the vehicles original 12v supply to fold out the mirrors when the ignition is turned on. My original design did just involve using the latching relay and it worked perfectly. We are effectively using the 12v supply going to the door locks to operate this relay (lock). When the door lock supply is reversed (unlock), the relay resets back to it's original state. Trouble is, when you are driving, what do you think happens if you lock the doors? The mirrors fold in while you're driving! Not a good thing.
The solution, was to interrupt the door lock supply to the latching relay whenever the ignition is on. This is why the second relay was added. Hope this helps.
