I went the other way with the idea & have a push start & toggles to run everything. I have a Master Power switch that turns on relays that control the ignition box, boost controller, meth injection, gauges & EEC. I have a switch that turns on the fuel & turbo oil return pump. A switch to turn on the lights. A switch to turn on the wipers. A 2 way switch to work the turn signals. A switch to kill power to the fan & alt at the track. If my car still had a heater, I would have a toggle for that too. Some of the guys I know say Im 1 toggle away from needing a pilots license to drive my car lol. yes its a wiring nightmare and I would agree that in most cases, if its not broke, dont fix it. I no longer have a steering column with a key switch or multifunction switch. Its just a shaft with a steering wheel on it. I only need a key to open the doors & hatch.
