All of my gauges work, except for the speedometer. The road speed doesn't show up on the computer, either. I have the 3M, from the stock harness, going to the road speed connection for the haltech and I also rewired the road speed sensor, on the tranny, back to the X-14 connector. Is there another connection I need to make somewhere??

 

Did you leave the stock harness in or pull out the whole thing?

 

Pulled out stock harness. I rewired the speed sensor connector, on the tranny, back to the X-14(white) connector, where the old harness plugged into...

 

In the manual it shows two wires going through X-14. Coming from the tranny they orange and green. That is in my 94 manual, sorry I couldn't find the pinout on the harness, but they should be near each other. On the back of the gauge cluster it is wires 3C (yellow/red) and 3A (yellow/white).

Just lucky that I have my shop manual at my desk at work

Yes, I have it rewired to 3c & 3a, but doesn't work with it that way...
