Mattax, this is what I was thinking of. I have the harness unwrapped under the dash to get the wire from the welded splice to the amp gauge cut and taped off, and the wire from the cab side of bulkhead to where I can splice new 12 gauge bl wire from where I cut off the bulkhead connector. Feed that newly spliced 12 gauge bl wire through the same new firewall grommet as the 2 new amp gauge wires. Run it to the new 16 gauge FL, which goes to the terminal block on the alternator feed line.

Meant to ask; what can I use to remove the connectors in the bulkhead blocks? I want to remove both black and red wire completely from the bulkhead blocks.

Thanks,

Joe
