Fan switch when car is off?
I was wondering if anyone knows how to make the fan switch for the radiator still work while the car is turned off. My old prelude and a friends accord still work once the car is turned off but the s2000 does not?

No, the S2000 does not run with the ignition OFF. Why do you want it to run?
The +12v power for the fans is ON constantly, but the ground is controlled through relays that are powered through fuse 20. If you pulled fuse 20 and supplied constant power to the socket (through a separate fuse obviously) you could make the fan run with the ignition OFF.
But that circuit also powers the radiator fan, condensor fan, AC compressor clutch, blower fan, and the heater control panel, which would run the battery down if left ON. You would have to do some serious wire whacking to separate the circuits. I don't see what it gains you.
