Just an update for everyone that contributed. I changed the instrument cluster to the 95 and installed the speedo cable and everything seems to work awesome! The PC Board was definitely different but all the connections were the same, the footprint was the same and best of all the Cruise seems to work without a hitch.
We did have to drill a hole the right size for the 95 speedo right behind the gas pedal. The 94 didn't require the larger cable and the speedo routed differently; but that's a small sacrifice for such an easy solution!
Thanks to all for the feedback. I've got a few more things to touch up on this conversion so I may have a few more questions.
By the way, I have enough leftover parts to build 3/4's of another 90-95 4-runner. Where'e the best place to sell them?
