Does anyone know if the signals are different pulses between a 91 system and a 94 system? I dropped an entire 1994 driveline and wiring into my truck and swapped in a 1991 k5 electric speedo. But it isnt reading right. Scanner shows proper signal at the pcm tho. I know the vss gets 40 pulses per rev. The 94 Vssb the sends i believe 2000 pulses per mile to the PCM and the Speedo. That right for the 91 speedo? Thoughts?
