Mine does not have one and i tried putting in one from what is probably a 4.3 auto and while the speedo and odometer seem ok, the tach is way off. It reads much lower than actual when i compare its reading at various RPM's against an OBD-2 realtime scanner. I'd like to source a unit from a 2.2 if they were ever optioned with one. Anyone know or have one?
Thanks,
Jon.
