Default '91 Civic: A/C as kill switch

I am trying to turn my A/C switch into a kill switch for my '91 Civic htbk. Does anyone know which wire is for the button toggle?

What car? See forum Rules sticky.

I hope you don't have and don't want A/C.

Fixed.

And A/C does not work in the car and I don't have any desire on fixing it.

You can get away with using just the blue/red from the A/C switch, it is a ground when any blower motor speed is on, it can be used to trigger a "starter cut relay", [turn a relay on], lust using it allows the A/C light to also work as an "on" indicator.

The switch will not "carry" enough current to use it by itself as the starter cut, unless your car is a 5 speed, [standard] then you can run the CIS, [clutch interlock switch] output or ground input through the switch, use the green lead into the switch for the input and the blue/red for the output, the A/C indicator light will still work. 94
