SD1 electric windows and DIY wiring

Post by spegru » Tue Aug 13, 2019 9:07 am

My car came without electric windows, so I retrofitted motors from an SD1.
But for the switches I made my own setup using simple buttons from ebay and some reasonably clever relay wiring. I actually used the simplified version with the diodes

Simple buttons. On for Up one for down each side. The middle button is for the rear hatch release solenoid

The original simple circuit has a fuse and switches which don't seem to give lot of trouble so why go to such bother unless you cannot get the original switches now.
