Why are you under your car? Isn't the sender plugged into the water jacket from the top? probably on the intake manifold near the water neck. could also be in the side of the cyl head. I dunno what colour the wire would be, but it goes to the relays.

Switch is on the passenger cylinder head.I think the wire is black, but the giveaway is the connector.Its round/grey & about 3/4 dia.On my car it comes out of the wire loom from above the valve cover & the loom is routed from the firewall.

Are you looking for the green wire maybe?

ok thanx for the help guys. turns out my car originally had the dual fan setup then someone b4 me took that out and replaced it with a single fan harness...so there really was no wire goin to the fan switch. i replaced the coolant temp sensor underneath the throttle body and its good now.
