    Ron Francis fan relay

    Looking at my Ron Francis fuse block as received, it looks like the fan control wire is not jumpered to the fan relay or any relay for that matter. Looks like they did not install a jumper at the factory. I am running a Gen 3 Coyote so I think I can bypass the relay anyway and connect the orange fan wire from the Coyote harness directly to the blue fan wire. Or is there an advantage to using the relay on the Ron Francis fuse block? Seems redundant as there is a relay in the Coyote module.20200531_180750.jpg

    I used the Coyote fan control, seems to work like a champ and turns on around 190 degrees. One wire and a ground, doesn't get any simpler.

    Yes, that fan relay is missing the main power wire from the fuse panel. Strange. But BraidCraig is right. Use the fan wire from the Coyote control pack and you're done. That's what's explained in the Factory Five Coyote instructions as well. Technically you don't need the RF fan circuit. Although it's a nice 30 amp relayed circuit. I used it for the auxiliary outlets in my build.
