So I think I'm having a brain fart moment. I'm going to be installing my Autometer boost gauge which has this auto calibrate crap and it wants a ignition turn on signal that doesn't turn off when the motor is cranked. You know like how your radio turns off when you are cranking the motor (assuming you had the keyforward and radio on prior) until the motor starts. It wants me to find a 12 volt source like that. Problem is I can't think of one. Cig lighters maybe? Anyone?

 

anyone?

 

The battery...

 

There are generally not too many of these. The first that always comes to mind is the positive lead to the ignition coils.

 

Thats what I was thinking too..where the hell am I going to find a source like that. Maybe the cig lighters? what about the stock gauge power?
