The VSS in the transfer case is in the same spot that the speedo drive would be(or where is IS when you put in an SYE).

As far as I know you cant drive a cable with a speed sensor taking up the same space? Plus.. for a cable drive the shaft has a gear on it, and with a VSS, it has a "tone ring" or reluctor.... SO.. you either have no speedo cable drive, and a VSS, OR you put in an SYE, use a cable drive, and have no VSS for the 4.3. I guess you could get creative, and fab up some dual output with a reluctor ring, and a VSS external from the output shaft. <img src="/forums/images/graemlins/confused.gif" alt="" />


It is perfectly clear... just not as easy as you think.
I think the best option would be to use the GM system, and controls.
