Reply to "Backup Reverse Light Switch Alternative?"

I have a series of 3 switches that start the car, the back-up lights are powered by the starter activator switch. They are 1) powers up all ignition, power to running process. 2) power to starter ( back-up lights ). 3) start button to crank engine. I have a indicator light if I start to drive without turning the # 2 switch off. Their is a couple of real reasons this is practical, if your in a full throttle jam you can just hit the switch, very quick kill switch, without locking up your steering wheel. The other benefit is since the starter is independent you can bump or crank the engine without starting the engine.
