Sniper and Trunk Battery help

The alternator charge line MUST be on the battery side of the cut off switch. If that is what you are asking.

Unless the cutoff has a MONSTER of a duty rating for the small terminals, there is no way I would run the charge line like that diagram. That is a REALLY old diagram and I can't recall running a system that way. I've been using CD relays for 20 years or so.

Running a system to the rear of the car, an 8ga wire is insufficient in sizing. It's a 12-16 foot run from alternator to trunk. I use minimum 4ga on that run.
