Wiper switch to motor wiring

[DizzyD]

Ok gents, I'm seriously about to just lose it. Have a 78 c15 that I have been restoring for a few years now. I ripped out all wiring which was severely chopped up and re-wired with painless harness. I see the light at the end of the tunnel but can't seem to get the windshield wiper motor and pump to work with the switch. I have searched this forum and the Internet for days now but can't seem to find a diagram that shows what wires on the wiper motor and pump goes to the switch. Truck has the non intermittent setup, worked fine before and motor works fine but I just can't get it to work with the switch. The wires that come from the switch harness are not all the same colors as the wires that come from the motor and pump harnesses. Any help is greatly appreciated.
