I'm installing a b&m hammer shifter in my expy console and will need a way to shut off my od. Does anyone know if the stock od switch is a momentary switch? I assume it is since the od comes back on every time the truck is restarted. If so I'm thinking I could just wire it into the cigarette lighter, push it in and it completes the circuit, wire in one of the spare unused lights in the dash for the indicator light. Anyone know?
