I have tried to research how to properly disable the 1973 seat belt warning system, since I don't want to deal with the switches in the belt latches or passenger seat bottom, but the only info I have seen so far is for '74 (with the starter lock-out). My hacked-up wiring has the round connector (for the latches, I think) but the 2-wire flat connector is missing.

Any guidance from the collective?
