Bratfix

Ok I am new on this forum and a shade tree mech.. The 86 brat I am working on, I traced the fan motor that is on the DRIVERS side. This motor is not associated with the AC. The wiring on this motor has led me to a relay located on the passengers side fire wall and this relay is also connects to a temperature probe next to the top radiator hose. I am however having trouble finding the cooling fan switch. Any help would be greatly appreciated.
