it should be but... on a 73 ? that is 74 ( unless a VERY LATE 73 )
Thats to reset the interlock function in case of fail. On interlocked cars, you need to fasten your seatbelt before start the engine. If you don't do it, Starter motor won't crank
more info ( and a video ):

PN... I have TWO PN according with Car built date:
Up aprox to 9-24-73...3746723
after aprox 9-24-73...3746901
now, dunno if is just a change on number OR change on function
That button won't decide if you can start or not the engine, Thats just an Interlock control box decision. Reset button is in case of interlock control unit fail. And in case of fail on that button, you still can crank the engine jumping the starter relay LOL
