73 vs 74 duster wiring harness

I ran mine for years with the seatbelt connection disconnected.

Since then I have rewired my dash harness to use a different buzzer so it only buzzes with the ignition off and either the key in the switch or headlights on, when the door is open. I also removed the seatbelt interlock module and swapped two wires in the bulkhead connector so the start signal goes direct to the starter solenoid.

The yellow wire off the ignition switch splits in the harness and one goes to through the bulkhead connector to the emergency start relay (relay with the red button on the side) while the other goes to the interlock. There is a circuit off the interlock module that goes to the bulkhead connector and to the starter solenoid. I just swapped the two at the bulkhead connector and now my ignition switch connects to the starter relay like it should.

I can look up the pins later if you want, but don't have that in front of me right now.
