84 Cooling Fan Relay Harness

I apologize if this is answered already, but I am in the process of diagnosing an issue with the radiator fan in my 84. I noticed the radiator fan relay harness was replaced with a generic aftermarket harness/relay and would like to restore it. I picked up a new harness from Top Flight, but it has six wires extending from the harness, all white. Is anyone familiar with one of these and the proper wiring?
