why does that have to do with his cooling fan switching on at the "proper" temp (not sure what temp exactly)??? he wants to run a second fan through a relay to a switch and maintain a factory appearance. use the relay you jumped as the basis. trace the wire that would go to the a/c side of the hvac controls, and wire it into a hot switch with either ignition on or always hot (whichever you want/are comfortable with). there are posts with wiring diagrams on how to do such a thing. a little time and patience will go a long ways!!
