I recently bought a 94 YJ for a good price, so I wasn't too concerned about the speedo not working. I figured it would be a fairly easy fix because upon initial inspection it looked like the speed gear housing was broken where it connects to the transfer case...that shouldn't be too bad.
I'm now working on this problem and have found out it may be more of an issue:
It appears that this YJ has the NP-207 transfer case. Did the previous owner have the original transfer case replaced?? I thought the 94 YJ's had the NP-231 transfer case.
The speedo gear housing that I removed from the NP-207 is a small steel cone shaped housing with a completely plastic gear in it.
I have the 1994-1996 Jeep YJ MOPAR parts list. It shows my YJ should have a much larger plastic speedo gear housing - which would match the electronic speed sensor that I have under my YJ.

My question is how do I get my speedo working / speed sensor attached to this speedo gear housing? Is the speedo gear housing from the NP-207 for a cable driven speedo? If so, is there any way to get that to work with my electronic speed sensor?
I would, of course like to get the speedo working without spending a fortune. This YJ will not be a hardcore rock crawler or mud machine, not even a daily driver. It's mainly a play toy for weekends and hunting, so I'm not sure I want to spend the money on replacing the transfer case....if that's even a good solution.
I'm not sure if I'm even on the right track with my thinking - so any suggestions are greatly appreciated.
BTW, I have the complete 1994-1996 YJ MOPAR parts list as a .pdf file if anybody wants it.
