I thought it might be a good idea if it's not too much trouble. I'm concerned about how the fan doesn't kick on til she's roastin', and then stays on for a long time. Sometimes even after I've got her back in the breeze. With a toggle, if I know I'll be stuck for a while I could kick in the fan before she got so hot, and cut it off the moment I got out of first.

 

I saw someone selling OE type radiator fan switches that turn on earlier, I think on fleebay. They weren't cheap or I would have picked one up while checking em out.

I have a simple rocker switch hooked in to provide a ground when I want it to like in stop & go traffic - it will still function automatically though if you aren't paying attention to it...

 

A rocker switch, so providing ground fires it up huh? Does the sending unit have one or two wires? Where did you mount the switch?
