Hi all. My 74 GTV had a rusted out Bosch DHP12 wiper motor, and I sourced a good Bosch DHA12 to replace it. The DHP12 has four wires: White, Blue, Blue/White, and Blue/Black. The DHA12 has three. White, Red, and Green. Any ideas as to how to wire this up to function? I dont mind if I dont have two speeds if thats impossible.

Thanks!

See below how I made my wiring using 3 separate switches, but the wiring of the motor is the same.
