I only ask as I'm sure my activa doesn't have them or if it does they aren't working so if worst came to the worst I was thinking of just getting the mirrors now they are about £5 each and I could just run wires to the HRW relay and earth them in the door as they aren't going to draw a lot of power.
I don't use the car much if at all in this current weather but as the car has heated leather it would be another nice thing to add to it
