Can anyone point me in the right direction on programming the vehicle speed sensor buffer on a '93 C2500 6.5 diesel? Years ago, when I put the bigger tires on, I found the info here on how to change the jumper links on the VSS buffer to keep the speedometer accurate with the bigger tire diameter. I'm likely going back to the stock tire size now and can't find that info. Any help would be appreciated and thanks for your time.
