Somewhere on the fuse block there should be a spot for fans....it should have a fan trigger circuit....that would go to the fan relays and then to the fan...but that info would need programmed into the ecm...not knowing whose harness you have makes it harder to guess.....can you get some pics?...is this a LS swap?
