I picked up the electro-motor unit at the pullapart and would like to make it work but would like to avoid buying the VSS adapter from jtr to keep my mechanical speedo unless it's needed.
Not sure about this unit but with no ECM, isn't it just keeping the throttle at a match for the signals it gets from the VSS?
Thoughts?

I dont think it will work with what you have. Just putting a VSS in andntrying to run it straight to the cruise most likely isnt going to be the correct signal. The PCM takes the VSS pulses and converts it to a different signal if im not mistaken, but I could be wrong.
If you have the factory cruise, it seems like it would be just as easy to adapt to your carb as the newer cruise module since they both will need to be modified to work.
But if you try it, post back and let us know if it worked.
