I need some help on wiring my GM 2 speed wiper motor.
it works by grounding one or two wires:
- no grounds = OFF
- both grounded = low speed
- just HIGH grounded = high speed
so how do I wire this into my car?
I was thinking about connecting a ground wire to the A and D on the schematic.
And then connecting the B and F parallel to LOW and HIGH connection of my GM motor.
this way the original wiring stays functional and when the Velleman module closes both relays it ground both LOW and HIGH to ground and thus activating the LOW speed of the GM motor.
