1994 Dodge Ram 2500 with 318. Can't seem to find why speedo and odometer don't work. Have replaced the sensor on the tranny and the rear end, replaced the instrument cluster and still no speedo. All other guages work. Checked the harness from tran to instr plug w tester, looks good. What else is left?
It is a 2 wheel drive.

 

2 or 4 wheel drive? Where was the sensor you test located? VSS is in tailshaft of trans or t-case, depending on how many drive wheels ya got.
