Battery relocation

If you make the runs longer you MUST upsize the wire carrying that energy. Otherwise voltage drop becomes an issue.

There are many ways to do a trunk battery set up. NHRA legal and other methods. Pick one, size wire correctly with protection and go with it.
I ran #2 battery cable from the right rear of the trunk to a mopar relay, (TRIED A FORD, IT GAVE UP EARLY) . The mopar relay is located where the heater motor was, (but that`s a diff. story), 10 gauge wire to the single wire 130 amp alternator under the motor plate where the fuel pump used to be. Original cable going down to the starter from the relay. No fuses, no cut offs, no breakers. Everything is installed to not short out or give any problems. There is more ways to skin a cat ! SIMPLE IS BETTER FOR ME.
