Helping a friend swap a 5.3 into a 1993 s10. Original engine and trans were already gone and LS along with a THM400 were installed. I have the LS running and now I am working getting the gauges and speedometer working now. The original VCM was a 16173782 which had the vss connected directly to the vcm. My question is what is the ppm of the signal expected by the instrument cluster for the speedometer? He bought a 16ppr before I got involved. I can calibrate/translate the signal if I know what the cluster is expecting.
Thanks,
Brian
