For MY21 Ford added rear sensors for airbags and seatbelts. Confirmed on another post were a guy with a Mach 1 was removing his rear seats and found new harnesses connecting to the seat belts mounted to the floor.
If you didn't order the rear seat delete from factory and you had the rear seats removed aftermarket, there are sensors for airbags and buckles in the back seat now. If you get picked the Rear Seat delete options those sensors are non-existent back there.

600A, Shadow Black, Tremec6spd, Handling Pack, Recaro seats and Rear Seat delete.

Most of that for the 2021 Mach 1s was late availability and they won't start building Handling Pack cars till after winter is well over cause Ford doesn't build cars that are packaged with Pilot Sport Cup 2s due to they will crack in cold weather.

I'm trying to figure out if something is wrong with my tremec transmission or if it's something that the 3160 just does. When going into 2nd and 4th you can hear this weird noise. Doesn't do it when shifting into 3rd. Clutch fully depressed when shifting through the gears and not slamming into...
