Thanks Rpg0, I thought you were on to something with the loose wire idea. The wires are all connected, and none of them seem to have been disturbed. I did notice that the alarm did not sound when I fastened the seat belt before starting the truck. It does continue to go off if I start up and then fasten the belt...but...the goofy thing might start bonging a mile down the road when I'm all fastened in and thinking it is healed.

I don't know anything about the switch you are referencing. Is it accessible, and maybe interchangeable from one seat to the other. I could test it that way..?
