Thread: Dual Cooling Fans Question

  1. #1

    Default Dual Cooling Fans Question

    Is it possible to run the Output #1 wire light blue with the Output #2 wire light green into the the same relay ground? I have dual relays for the fans, and would like both fans to come on at same time. My wiring harness came from American Autowire with the dual relays for the fans.

    Not sure how your relays are wired, but I have dual fans & two relays. I'm using just the single light blue wire to trigger both of them.

    Does it matter if it's the light blue wire or light green wire to trigger both. Thanks for the info.

    Light blue is Fan #1 (Output #1), might as well use that one (LINK - page 17 & 50). They operate in numerical succession.
    May God's grace bless you in the Lord Jesus Christ.
