Dash harness replacement and upgrade.



Found a wire burnt up through my whole harness. Yellow wire from bulkhead to headlight buzzer connector. Traced it back and someone had spliced it to the red wire leading to the tail lamp harness. Headlight switch connector was melted and found multiple shadetree splices and melted insulation throughout. After having to unrap it all under the dash I feel like it's not worth saving.
I bought a nice used harness from a member and enough brand new connectors to replace all bulkhead and headlight connectors with a few to spare. I will be bypassing the amp guage and running 10ga through the two empty slots in the bulkhead for power wires.
Trying to decide the best way to tie the ammeter wires together without snipping them. May add a voltmeter but not sure if I want to put it in the cluster or in a pod.
Also want to add a fuseblock to power my auxillary guages, MSD, electric vacuum pump and electric fan relays and relays for the headlights.

Just looking for some good ideas and tips on how to get this accomplished cleanly without removing my dash altogether.
