dpbayly is on a distinguished road
Just wired my power fold mirrors to my ignition to auto fold in/out

After retro fitting the power fold mirrors with the switch module a few months back I always folded them before leaving the car but a few weeks ago both mirrors became intermittent responding to the switch so I decided I'd re wire them to auto fold,

so I set about investigating how there wired armed with my Power Probe I discovered the motors have 2 wire and there fed with a + and - to fold them in then the polarity reverses down the wires to make them go back out so I knew I'd need a dpdt relay (double pole double throw) I also discovered the + and - was only fed down the wires for 10 seconds or so before they became nothing so I then knew I'd need to source some timer relays and Id need 1 standard 5 pin relay to activate everything off the ignition.

So picked everything up and set about drawing out the wiring diagram (looked like spaghetti junction wires everywhere) after I checked and double checked everything for back feed issues and things i then set about hooking it all up, I managed to do all the wiring in the passenger footwell behind the glove box where the fuse box is located so I could tap into an Ignition switched + and a constant + and a - all one place and all I had to do from there was lay the wires through into the doors to tap into the mirror circuit.

Anyway here's the finished product:
