Ok I've looked through the online 1993 Toyota Service manual, but can't find any info on the wiring or the sending unit for the low fuel light. Here is the situation:
1994 V4 4x4 extra cab DX, but has the gauge package (large tach/speedo & fuel gauge on lower right) 4 small gauges, 2 large.

I have the dash apart now so anyone know if the little orange warning light is just a bulb I can try to replace ? Or how would I test the sending unit which I assume is in the tank or near it ?

Thanks,
Tried doing on a search on these forums...found nothing.
