I mounted the switch for the Hydrogen Generator directly under the dash using switched power from the ignition switch. I left the wires exposed here so you can see that I will hide the wires behind the steering column and then tuck them behind the carpet on the floor where it will run to the back seat area. I have added an oil temperature gauge to this car so there is another wire for that already there. Making sure to used switched power from the ignition switch (off when the ignition switch is off and on when the ignition is on) I will be sure this unit cannot be on when the engine is not running.
