What kind of valve cover is that??
I am pretty sure that is the seatbelt interlock that was used in 74

Its the seatbelt interlock, if that goes bad your car won't start!!! Don't ask me how I know!!!

That is for the the seat belt, but I was always told it allowed you to start the car from under the hood without the need to be butts-in-seat with the belts hooked up. That's why it has a button on it. If you're starting the car using a remote switch like a mechanic would (or a screwdriver across the relay terminals like we do), you would press down that button and it would bypass the safety circuit on the seat belt system and allow the car to start.
