is there a way to relocate the battery to the spare tire well without running the alt wire to the battery side of the master cut off switch? So that the car will shut off when the switch is turned off! I don't want to run another wire all the way back to the switch if I don't have to. Somebody told me that it could be done with a relay but I still need a wiring diagram to figure this out .does any body know the right way to wire this. I did a search but couldn't find any thing.THANK YOU FOR YOUR TIME
