Simple re-wiring

I'm not sure the word "simple" fits in with your question

There are many aftermarket harnesses, and there are a number of pitfalls with the original harness, quite a bit centered around the bulkhead connector

Painless, Francis, American Autowire, we've been down these threads before.

One complaint I have with some of the aftermarket stuff is that it's pointed more towards GM than Mopar, and some don't actually come with a complete diagram

THE BIG PROBLEM with factory wiring in these cars is

connectors............any connector. Connectors at the headlamps, the bulkhead connector, the fuse panel, or any of the switches.

especially the bulkhead connector

ammeter.......wiring is too small and again........bulkhead connectors, and the ammeter itself is poorly constructed, depending on year / model

headlight wiring is marginally small for modern hi wattage bulbs

under fused. The older the car, the more "under" fused these girls are.

Always a good read are the articles here, especially about the ammeter / bulkhead connector, and headlights
