Electric Fan Wiring

I don't have a fitech, mine is a fast 2.0, it has 2 trigger wires, fan #1, AND FAN #2, I USED FAN #1 TO TRIGGER A RELAY----------
Hi,

Thanks for taking the time to reply. I will use the Fitech to trigger the fan relay as well, but don't know where to run the white relay wire to on the factory harness...
