[QUOTE="Walt Jaquith, post: 428889, member: 18654"] I'd put the temp sensor as close to the engine as possible, but I don't see why that wouldn't work. Just make sure you get it in the send line, not the return. It would take a relatively hefty PWM/FET unit to run a radiator fan; those things pull a lot of current. I'm not sure the fine control would be worth the effort. I've thought about getting an Arduino (or similar) microcomputer and programming it to run the heater fan, auto-on for the lights, wiper delay, and several other things of that nature, just for fun.
