bypassing interlock system

Hey BigD, my 74 still has all of that on it. The plugs under the seats have been unplugged ever since I've had it. I got it from original owner at 42,000 miles. Dug into it one time and pulled the reset switch under the hood apart and found the contacts had been soldered together.

The blue box your talking about, is it the one mounted right above the fuse box? If it is, I've wondered what that was for the past 20 years. What exactly is it? All I see inside it is a circuit board.

Also, is there a key or seatbelt buzzer on these cars? I've never been able to find one. I know the earlier ones are mounted beside the glovebox compartment.
