I was wondering if anyone is familiar with the way the seatbelt/key in the ignition buzzer works and is wired.

I was looking at the schematics for a 74 model year, and I'm not positive they were the same as my 72.
Is there another control module other than the buzzer itself (which is on the right side of the dash)?
I have a couple of extra connectors on the right side of the steering column that look like they were once hooked to something, but aren't now.
The reason I ask is that the seatbelt warning light, and the key in the ignition buzzer don't seem to work (buzzer works if I feed power to it). In order to pass my safety inspection, everything must be in working order.

I read in the 74 chassis manual, that there is a "Seatbelt Interlock Control Unit" beside the steering column, and I'm wondering if that is what's missing on mine.

If I'm right, pictures of this unit would be greatly appreciated.

Thanks,

I had to rewire my entire dash on my 73 with a harness from another car. I ordered a beautiful diagram from www.classiccarwiring.com. It really saved my bacon. The entire car's wiring is on one sheet, making it easy when you're on your back under the dash. The diagrams are clear, everything is well marked, and the double-sided sheet is laminated (a must). I have it here but if I tried to explain where your seat belt wires go I think I'd just make it more confusing.

Hope this helps.

I could be mistaken, but seems to me years ago I had a problem with this. Isn't there a module on the fuse block that controls this? If I have time tomorrow I'll take a look. I have a 72 SSP with all the bells and whistles, and the harnesses have not been modified - still stock.

I have a 73 the key in ignition buzzer/horn relay is plugged in the fuse panel and the seat belt buzzer is in the right side of dash.

Got it all working this weekend. Turns out it wasn't missing anything, but just had a bad ground. Also got the entire interior installed this weekend.

Just have to finish the engine and trans rebuild and finish up a few small details and I'm ready for the road.
