need to tap into "true ignition source", have diagram, wondering what fuse is best?
Wanting to hook up a 200amp isolator to separate two batteries. One lead has to go to a true ignition source.
I want to use an add-a-circuit and plug into the fuse box underneath my steering wheel.
Of the fuse locations listed, what would be a "true ignition" source? I'm assuming that is just a 12V ignition line...i'm guessing the radio would be ok for that, or the ignition coil? What is the smartest fuse location to use?
