Battery relocation wiring

"In my opinion" (read the rules a few times) running a separate wire from the alternator to the battery violates the intent of the rules.

Also, ask YOURSELF, when you are upside down in "that thing" with gasoline dripping everywhere, do you REALLY want a hot alternator wire welding around here and there?

What I like to promote is a 4 terminal switch known correctly as "double pole." "Someone" is now making one with considerable contact ratings. That is a large pole (2 contacts) for main battery and a pair of smaller terminals. The small contacts ARE NOT intended for a lot of current

Run a pair on no14 wires back to the small switch contacts. There's a number of ways you can implement it. Use it to break the EFI pump relay, ignition relay in series with the key, etc. Several ways to do that.
