Need some advice
I'm sure you can hook up the bottle heater to a switch by cutting the wires.This is new to me too <img src="images/icons/confused.gif" border="0">
I would run a window switch for cutting the N2O before the shift.This will extend the life of your tranny.
Like slowhawk said, just cut the cigarette adapter off and hard wire it to a switch. If you're not sure which is pos and which is neg, plug it into a cig lighter and then poke the tester through one of the wires. (i'm not trying to be a wisea$$, not sure of your electrical experience...)
