I've seen stock eliminator cars with a master disconnect on the rear panel. That seems really nuts to me unless there is something else going on with the wiring that I don't know about. If they are running a hot cable all the way to the back just for a disconnect switch then it seems like it is less safe than not having a disconnect.
With a battery up front and no disconnect switch there isn't a lot of hot cable. For my car I'm going to use a Ford type solenoid so the starter cable is only hot while cranking. So the only hot line when the key is off is the BATT feed to the fuse panel under the dash.
i don't have the wiring diagram handy to post. but there is a simple way to use a switch at the rear using ten gauge and smaller wire.. it just controls the relay mounted in the front. it has to be a snow plow constant power style relay.
