Hello I'm not sure if this is the right way to contact you but I installed powerfolding mirrors on my car and connected a relay Box that goes with the mirros. There is only one 12 V wire that controls the mirrors for opening and closing. Every time this wire receives a 12 V pulse the mirrors will extend all the way and stop or close all the way and stop. The reason why I need a 12 V pulse is because because if I give it a constant 12 V the mirrors will open and close rapidly without stopping I need to figure out how to build something that will give me a 12 V pules when I start the car and another 12 V pules when I shut off the car. ThanksYou've been waiting a long time to say that, I'm sure ... I've not been posting much in the last few years.
