Her69fastback 3 Report post Posted May 9, 2022 To all the wiring gurus. I have everything wired & to car runs. I’m trying to figure out the double fan wiring. I have 2 relays on the way. I have 2 electric fans. The Holley snipe will control the fans. What’s confusing me is they say the Light blue & light green wires are output connect to relay ground trigger. I’m a dummy when it comes to wiring. I have searched the wed & it’s more confusing. I found this pic & I think this is how I need to do it. I want someone that’s knows a lot more then me to look at it. Quote Share this post Link to post Share on other sites

Mach1 Driver 560 Report post Posted May 9, 2022 Yes its correct, the Sniper instructions say the blue and green wires from the 10 pin plug go low (go negative) when turned on. These wires go to 85 which is one side of the relay coil, and 86 is the other side which goes to battery +. That operates the relay and 30 to 87 closes applying battery + to the fans, the other side of which goes to chassis. Quote Share this post Link to post Share on other sites
