Looking for just that. If you could have a new harness your way, what would you do? Bulkhead disconnect or gromets with hardwire passing through? Ignition options? Wire colors? Whatever would you do?
As a starting point I used the original stock under dash harness and replaced the engine, forward lamp and rear harness with Year One reproductions. But, here's what I modified: 1. Repaired and thoroughly checked under dash harness and cleaned bulkhead connector 2. Ammeter bypass, changed to voltmeter 3. Hard wired BATT and Alt voltage throughout vehicle bypassing bulkhead (used grommets and terminal blocks) and increased wire gauge 4. Kept bulkhead connector for all other circuits 5. Moved battery to trunk The "pro" to using this method is that the Factory Service manual wiring diagram still applies, except for my modifications, and for those I created my own schematic and the system looks "stock" under the hood. I have a very simple system with no added electrical components. The one thing I would add is a distribution block under the dash for switched 12 volts and Batt 12 volts to make it easier to add accessories.
