Can anyone explain this seat belt warning light schematic to me?
86 - 12v from the buzzer. 15 - 12v from the ignition switch. G - Ground through the seat belt receptacle switches. (Is your seat belt latched?) 50a - ???? I have 1 car that doesn't light up at all and another that flashes. I thought the seat belt light was not supposed to flash and didn't have anything to do with the e-brake switch. Thanks.

Thanks Jeff. That stuff is the seat belt interlock system. This diagram I posted is actually a little circuit board inside the red Seat Belt light on the dash. I think I have it figured out now. I don't understand what the resistors are doing, but I understand the broad picture.
Oh well. |
