(my guess is the wire is + and the engine - )

The fan running whenever the ignition is on usually indicates that:
(1)the temp switch is bad, (you eliminated that one)
(2)the temp switch wire is broken
(3)the air conditioner high/low pressure switch is bad
(4)the air conditioner reridgerant pressure is so low that the system won't work
(5)the air conditioner high/low switch wire is broken
If the temp switch wire touches the engine it should not affect anything but the fan.
The temp switch grounds the wire to the engine when it is cold, and opens when it is hot. So that wire is normally grounding to keep the fan from running.
