Convenience Center Tester

I've wanted to better understand the mysterious convenience center, tucked up in my dash where I can barely touch it. I finally got my opportunity & pulled one out of an '80 Grand Prix in a local junkyard. Then I built this Frankentester to verify my understanding of how it worked. And now if I come across these components in my junkyard & swap meet travels, I can test out of the car.

I also have a newer Lectron chime box & it has three more wires. I'll figure those out & incorporate them into all of this.

Very interesting. I'm curious too.

Very interesting. I'm curious too.

I think in 1981 the seat belt & ignition buzzer (two parts) became one in the blue Lectron chime box. The ignition buzzer comes out & the harness from the blue box goes in it's place, and the gray wire from the Lectron box goes to the fuse box.

My 'blue box' is dead so I can't test this.

My 1981 service manual had always confused me because it seems to show both old (gray) and new (white) components. I wonder why?
