You can use the wire that goes for the coolant over flow tank sensor. It is only on when the key is in the on poistion.

ok fan is all installed and runs killer.. its one of those new Black magic extremes' pulls 3300 cfm @ 18 amps, this fan is sweet!
anyways my last question, what temp do i want the sensor set at? I have a 180 degree thermostat and the engine is stock cept for pullies/exhaust ect.. do i want to set the fan control to 180 degrees as well?

If you have the fan set to 180* (I assume you mean to use 180 as a turn-on temp), then the fan will pretty much run constantly during the summer. Not what I would want.
I would set it so that you actually (and by actual I mean create this situation dynamically with your own instrumentation - some/many adjustable controllers on/off rheostats are very inacccurate) it turns the fan on at ~195*F and turns it off at 187*. That way the stat has a chance to open and try to cool before the fan comes on. The actual temp at which your stat opens depends upon the stat used (Balanced stats open more reliably).
Good luck.
