SPEEDOMETER

[90RATZILA]

I have a 1990 suburban w/a 454, 465, 241tc. The computer was
removed because of tbi to carb swap. Does the speedometer
work off of the computer.I have checked the wires going to
the transfer case & they seem fine.
THANKS FOR YOUR HELP

Yes, it is run from a VSS (vehicle speed sensor) which the computer controls.
