Wiring schematic for retractable seat belts.

[JLPurcell]

I need help. I am working on all of the little things that do not work on my 1972 Z (production date 7/72). My seat belt warning light is not working.I have multiple wiring schematics but none of them show the wiring for the seat belt warning light with the retractable seat belts with the pressure switch in the passenger seat. In my testing last night I have found that the circuit is open on the seat belts when they are in the retracted position and go closed when the seat belt is pulled out. The passenger seat switch is normal open closed when pressure is applied.  Anyone have a working diagram of the wiring? Any help would be appreciated.

Thanks JLP

 Because updates didn't follow model years, I'd check the 73 wiring diagram. 7/72 could, and likely does, have had some 73 updates.
