MG MGB Technical - How is the 'buzzer' mounted?

Hi,
I'm helping someone figure out the wiring behind the radio console in their earlier 1973 MGB. We have it all figured out. We were missing the buzzer and diode amoungst other thngs. What I can not remember is how and were EXACTLY the buzzer mounts. I know it mounts on the metal vertical dash support portion behind the radio console, below the dash and above the gearbox tunnel (where the hazard flasher unit mounts), but where exactly? The buzzer looks like a little can with a tab off the top for a screw to fit through. "I used to know this!"
Thanks,
Paul B.

As you look at the vertical dash support, it should be on the upper left, over the radio. It's on the inner side, opposite the vent door. The only way to see it is to crawl under the dash. There should be a small wiring harness to operate it. The sequential module attaches on the upper right side. You'll see a plastic plug in the wiring harness that goes to the sequential module. You need a short stubby phillips screwdriver or a right angled ratcheting screwdriver that holds a phillips bit to get to the buzzer.

Now that you know where it's located, the next logical question is, "why would anybody in their right mind want to have that annoying buzzer hooked up?" ;o)

Buzzer?
Sequential module?

US only. There were several iterations, from a relatively simple 'key in and door open' and 'in gear and (drivers belt not fastened or passenger seat occupied and belt not fastened)' warning buzzer in 72, to a much more complicated sequential interlock system that prevented cranking in 74 and 75 together with the son et lumiere, to a simpler system again from 75 that just sounded a buzzer and lit a light for a period if the car was cranked without the drivers belt being fastened.

By comparison the UK only had a timed 'fasten seatbelt' light from 77 on if the car was cranked without the drivers seatbelt being fastened.
