Bad news, No Trucks in Pull-a-part with seat belts. So rather than fix the seat belt switch, I took an easier route. I swapped out the box for 1991-1996 Roadmaster/Caprice box. P/N 10092866
It works great but has some differences from the truck one:
- The original Truck one had a solid tone that sounds like a flat line on a heart monitor. The new box has a pleasant Ding-Ding sound that get faster if you leave the light on or the key in the ignition.
- The seat belt light is controlled by the box, not the seat belt retractor like the original was. The new box lights the seat belt light on the dash and dings for 5 seconds then both go off together. On the original chime box, the tone would go off after 10 second but the light would stay lit until the seat belt was puled out and the switch opened. Which was a problem with my switch. If i disconnected the retractor, neither the light nor the dinger would work. (thinking I already fasten my belt.)
- This new box has an additional 2 wire plug. This is for the turn signal minder option on the Roadmaster or Caprice. If you travel a preset distance with the turn signal on, it will start to ding until the turn signal is turned off. Helpful on a Buick for sure. This plug just needs a signal from the electric speedo and the turn signals. Even though I have electric speedo, I will probably leave it off.
However, for my intended purpose, it works great. The seat belt warning, Key in ignition warning and headlight on warning all work. And I didn't have to replace or recreate the retractor switch. Its alot of trouble just to have the warnings work, but I like it to see things work when they can. Also, during COVID, I had nothing better to do.
