Thank you Snowtoy! Is there a way to determine which color wires are for which function? I am assuming that the fan may be from a GM vehicle...the radiotor is a Harrison GM aluminum and it looks like it was all meant to go together.

Wires...large red directly to battery positive
large blue runs out and back into the fin area from what I can tell
large orange that runs 3 inches to a fuse and then back
two small grey wires run together and are held to the upper radiator hose with a rubber sleeve...looks like it could be some type of sensor on the end?
small green that is tied off with nothing attached
small yellow that WAS attached to the system somehow but I cannot remember how
small black that runs to battery ground

I can handle most things mechanical but have never had to learn electrical...so I am lost! The relay has numbers 85,86,87,30...it is a 30A relay. It seems most of you know what these numbers mean but I could use some help...which is ground, power, etc.?
