Hi All - struggling with making an 89 Ford wiper motor function correctly without the original factory switch. The factory switch had 7 terminals and no relay, here is the factory wiring schematic:
I have a universal 4 pin wiper switch and I can't figure out how to get this to work with a combination of this universal switches and relay(s). I've got a number of 4 and 5 pin relays availiable.
Essentially how I understand this is the Green wire needs to the power yellow wire (when running low or high), for Low, the blue wire needs to be grounded, and for High, the white orange wire needs to be grounded. Then for Park, the red wire needs to power the yellow wire and blue needs to be grounded via Black-White instead of the standard black ground wire.
I can get it to function making those connections manually but I can't figure out how to make it work using the universal switch. No idea they were this complicated.. can anyone please help?!
Thank you!!!
