Need some advice! Got a new L83 and using all OEM parts in my 72 C10. Got the radiator and fan assembly (Bosch motors) and need to control the PMW fans. Vintage Air to be added later which will be stand alone. I've got the big black and red wires coming from the fans and a smaller wire that I do not know what it does. Can't get any info from ACDelco, General Motors or Bosch as it's "propriety"??
What is my best option with your product?
