1974 duster starting issue

I believe mine is attached behind kick panel under dash. I don’t have that on the fender. I have heard about the seatbelt relay but I thought it was already bypassed because the wiring under the seat isn’t connected. Will check it out and reply with results.
It should be on the fender apron. If not either you maybe ?? have a very early model 74 that skipped by without it, or someone has bypassed it
