Well...I did it. I bought a new(used) truck that the PO had put the electric fan conversion in. Coming off of the fan are a bunch of wires. There was also a non-functioning air horn that I took off. There were two wires jammed into the fuse block in the cab and running into the engine compartment to a relay. The only wire I disconnected from the fan was yellow and also went to the relay... I took the relay off assuming that it was there for the air horn. I am unsure how to reconnect it all to get the fan running again. The fan has a blue wire that takes temp from the fins of the radiator. There is a green wire coming off the fan that is not connected to anything. All the larger guage wires remain as they were. Any ideas?
