I am installing a battery-isolating contactor under my hood, which will connect my starting battery to the deep-cycle battery in the rear of my truck, which is there to help with my high-amperage 12V air compressor. I only want the batteries connected when the alternator is running, so I'd like to know the easiest or best place to tap a source of +12V ignition power from.
I want 12 volts that is only available with the engine running (ignition switch pos 2) not accessory power like the stereo gets.
