It has a module that connects a seatbelt sensor and several other sensors that control whether the car will start. Hopefully this makes sense. The goal is to bypass this. Any assistance will be greatly appreciated.

Make sure the the "grn" terminal on the starter relay is being grounded in park/neutral via the NSS switch (in trans or clutch pedal) or just ground the male "grn" terminal on the starter relay to the nearby starter relay case mounting bolt. This will negate the safety feature & let it crank/start in any gear live every 24 hour block of time like it's your last day on earth

I know very little about E bodies but he told me the car had the system on it and it's a 72. I'll verify. Thanks again! I can always rely on folks here for help.
