I would save the original harness in case you need to use any of the factory specialized connectors ends. When I redid my B body I used a better through the dash connection for the heavy Alt/Amp flow, the factory bulkhead connector is a weak point for this.
Good luck!
Yeah I’d heard the bulkhead connector was a weak point, apparently only rated for a something like 35 amps, which was adequate at the time, but far too low now.
I’ll look at better connectors to go through the firewall.
I definitely plan on keeping the old harness. The engine bay one is in good-enough condition, it’s then trunk and underdash that are messed up. But i figure replace it all at once and so I have a reliable building point going forward. But that old harness will stick around for reference and just in case i need it
