MAD ELECTRICAL?

A variation on this is to run parallel wires through the bulkhead and instead of splicing, use ring terminals on the end and the ammeter stud(s) for the junction.
If not keeping the ammeter then this would require an stud insulated from the chassis.
If keeping the ammeter, it allows the option of bypassing it (everything attached to one stud) or keeping it in the charge circuit (wire from alternator to one stud, wire from battery to the other).
Some on the mopar forums call the parallel wires to the ammeter the "NachoRT" bulkhead bypass since he first posted this.
