Electric fan w/ F.A.S.T

[foxspy]

Hey guys,

Right now I have my electric fans on a relay and a thermostat, but want to hook them up to the F.A.S.T. I'm not good w/ wiring, so here's my question. The single wire I have going to my thermostat, can I just hook that wire up to the F.A.S.T and everything will be set to go??

How do you guys wire up your fans using the F.A.S.T and a relay??

Thanks.

The FAST output provides a ground at a preset temp to trigger a relay. If you thermostatic switch or whatever you are using provides a ground to your fan relay then yes you connect the wire to the FAST output and then configure it to turn the fan on and off when you want it to. Otherwise you will have to rewire it to work this way. If you hook 12V to the wire coming from the FAST you will burn out the driver and will have to send the ECU back to be repaired so be careful.
