Help- can't find a wiring schematic on the seat belt warning system. Light over the rear view mirror won't go out at times with the belts fastened and won't come on at times with the belts not fastened. Have schematic (23 pages) labeled 2000 MRIC and Snap-on Tools but if it is in here I don't see it. Nearest dealer hasn't been to helpful and the local library has nothing. Any idea where I can get wiring schematic or information? Any ideas where this is powered from? Thanks for your help.
