70 wiper wiring info needed

[Truckhead]

I would appreciate it if someone had a schematic for the wiper motor/switch wiring. Basically, I have 2 connector plugs from the motor and one from the dash wiper switch.

I bought a chassis wiring diagram but that doesn't help here. I believe the dark blue is the + into the wiper switch middle contact (of 3), but, after that, I'm not sure. I just rewired the whole truck and this is one of the last things to do.

Thanks in advance.
