Should work just fine, as long as you put in the correct ratio adapter. You'll need 2 cables: One from the trans to the RA, and then another one connecting the RA to the speedo. Exactly what RA you may need will take some guessing and experimentation, depending on tire size, etc.

I suppose it's not outside the realm of possibility you can just hook it up with one cable and it will be close enough.

 

my speedometer is not working at all nor is the cruise control. Looks like a vacum powered cruise control as there are lines from the vacumn assist on MC. The fuse is a 2 amp and it looks good. The VSS looks good but the nut was loose which I tightened.

any ideas?
