Yes that’s used as a ground for your relay and controls the fans.Vegas not sure if you remember this from this far back or if you still have it setup this way but, you took this white wire on the FPS harness: (should be 57 on the ECU pinout?) http://www.dsmlink.com/images/forums/1GECUPinout.pdf
and connected it as the switched source on the relays? or to the ground on the relays as a switched ground?

I'd like to set my fans up this same way (obviously with 2 separate dedicated relays)
