Fans....? What fans? We dont have no stinkin fans man... J/K What kind of fan is it? I worked at FAL for a few years, and depending on what fans you are talkin about, some are not made to run for more than 1 hr before they overheat or burn up. Also if you have a constant fan (if its fairly large) it will draw alot of power from your electrical system, and can put strain on a stock system, (which is why race cars have HO alternators). So what are you trying to do?
P.S. A small fan or 2 small fans, on a tranny and oil cooler will be alright, but anything larger than that may cause power loss and problems.

I still like honda's. :-/
in my camaro i have my dual fans hooked up the the radio fuse. So when the key is on, they are on, and if my radio don't work, i know my fans are not on.

Wire in a thermostatically controlled relay set to around 180*F. If you don't know why, you need to study up. I'll be happy to make a long-winded post about it if you like, but suffice it to say a constant running cooling fan is a really bad idea. I run a Permacool 16" electric fan along with the Permacool install kit set to ~180*F replacing the stock clutching fan in my RX-7, so I'm very fimiliar with the situation.
Super redneck engineering. :doh:

12volts with ignition on.... easy cheesy man. There is a group of yellow/black wires on the driver's side near the firewall. Splice into any one of them. But do so to a relay, no way are those going to drive a fan directly.

Hmm, ok, do what you will, but just remember, I have done this befor, and worked at a place that makes, and installs fans and coolers, and I know that this is not a good idea.... Like Kai said, get a low temp relay, so it turns on at a low temp instead of waiting untill it gets really warm. That will be your best bet.
