Mk2 Cortina wiper motor wiring

[vdo]

Hi peoples.

Can anyone help me out with a sensible wiring diagram, hand drawn or otherwise, for the wiper motor on a Mk2 Cortina.

It's a SINGLE speed motor, 3 wires.

I have an original wiring diagram but it gives no detail on the switch/park system etc. It just shows the switch as a rectangle with 4 wires coming out, that doesn't help.

Just want to figure out the operation of park etc.

Thanks in advance.
