Trust me if I had a better picture I would post it. I have two pictures of the engine compartment both are from 2000/2001 neither one is very clear or the best quality. Im thinking its not the seatbelt as i do not remember a red button on it. It seems to me it was just a silver relay with a red wire connection I don't remember a button. Maybe a horn relay?? Im looking thru the wiring diagram and the fsm and I don't see anything on that side.
