Alternator Upgrade and Bulkhead Disconnect

Charge line wire around and relays take loads off the bulkhead connector. It's that simple. Where you source the power for relays is a HUGE consideration on these mopars with an ammeter. Some relay kit sellers give poor advice and instructions regarding sourcing power.

If you only have to feed the interior requirements, without any additional loads, the factory wiring in good shape works fine.

Run a new switched wire to a voltmeter. Using the ammeter runs keeps the voltmeter ON at all times. The wire for a voltmeter does not have to be as large as the ammeter wires.
