switched 12v source that does not break voltage during engine starting/cranking. The boost gauge has an auto zero function, basically it takes a pressure reading during startup for varying altitudes and it will give innacurate readings if the voltage is broken during start up. Been so long since I started the car that im drawing a blank here, pretty sure the stereo cuts out during cranking. Ill be using the clock harness for the illumination wiring and ground, but not sure if breaks voltage during starting.
