Hard wiring lights?
it is nice to have the connectors like stock so that you can take the wire harness back out later on for service..... if you pass the wires thru the firewall then to your light connectors how do you get the wires back thru the firewall without cutting them?
I've heard this argument.
1---Just how many times do you visualize doing this? Maybe once, twice in the "life" of the car?
2--Unless you weld up the huge hole for the bulkhead connector, there should be just about nothing that won't already fit through the hole. So a simple patch, screwed to the firewall, can be removed and the harness fed right through.
3--There are many cars (back then) which had NO harness connector. That is, feeding the wires through the firewall is "how you did it." Chevelle comes to mind
Mine is now sort of a "morph." The original connector has become a simple feed through for much of the wiring, with the exception of the wiper connector, which seemed handiest to leave as-is. I no longer have an ammeter, and in fact have an aftermarket harness, so the only "high current" wire is the in-feed from the battery. Ignition, lights, etc, are all just firing relays in the box in the bay. Turn signals/ parking lights still run direct off the switches, no relays there.
