Re: Wiring my auxiliary electric fan.
a cool idea I would do is hook it up to a thermo switch. Find one in a junk Rabbit or something, and solder the fitting into your radiator. There are a whole variety of temp sensors you can screw into the fitting. I has one wire in and one wire out, doesn't matter which is which, and will turn the fan on automatically whenever needed. You can even wire it directly to the battery so there are no wires running through you fenderwell. It will act like all those other cars that say "Caution, fan may turn on at any time". If you are having an overheating issue, it will continue running until it is cooled below whatever temp the switch is, even with the key off. I wouldn't worry about battery drains... my Porsche alternator hardly puts out any amps and that fan will stsay on for a few minutes afrte the car is off and it5 has never needed a jump.
