That's what I was looking for.

I'm still trying to square away my VSS since swapping to the T56. I have the Dakota Box to convert the T56 VSS signal to match my ECM but I need a speedometer in line so I can see what it is reading in order to adjust the Dakota box for the correct signal to the ECM.
