Thread: Fan #1 & #2 Wiring

  1. #1

    Default Fan #1 & #2 Wiring

    I have a '68 Chevrolet 396 Chevelle that was setup with a Holley throttle body with the ECU. When bought, it had a clutch fan and original radiator. I bought a Champion four core radiator with dual fan kit. My Input/Output harness off of the main harness is a 3-pin connector. I bought a connector harness from Holley thinking that I could plug it in and operate the fans off of this part of the harness. Unfortunately, I got the harness and it was an 8-pin connector in which I found out that the throttle bodies only have a three pin. Anybody know how to wire the three pin into my Champion relays that came with the fans? Thanks for all your help!
