Darren Posted July 29, 2009 Share Posted July 29, 2009 just get a new gauge cluster from another cherokee or comanche from the same years, and it will swap right in. Link to comment Share on other sites More sharing options...

Automan2164 Posted July 29, 2009 Share Posted July 29, 2009 The dash comes out super easy, once you have it out, its pretty straight forward... Rob L. Link to comment Share on other sites More sharing options...
Eagle Posted July 29, 2009 Share Posted July 29, 2009 my comanche is a 89 and the cherokee dash is a 94 It can't be done. Your truck has a mechanical speedometer. The '94 XJ has an electronic speedometer. In addition, the polarity of the fuel gauge is reversed, so the '94 fuel gauge in your truck would show empty when the tank is full, and full when the tank is empty. You need a gauge cluster from an 87-1/2 to 90 Cherokee. Link to comment Share on other sites More sharing options...

Its in the MJ projects as "1987 SB 2wd --> 4wd HO conversion " EVERYTHING needs to be swapped, NOTHING is interchangeable. Best get yourself an entire vehicle to work with...No way I could've done it w/o a complete donor...at least not as easily and as cheap. LOTS of new/different things under hood, under dash, etc. and lots of little wires, vaccume tubes, nic-naks and trinkets that I have no clue what they do, but I swapped them anyway!!! I basically stripped my MJ to a shell on blocks, then stripped the donor, then began the transfer of parts. And no, as mentioned, the dash gauge cluster is different. Its actually amazing how many new/different parts swapped, that there were already mounting holes (never before used) in my '87, but these things didn't come along until the chrysler era...its like they could predict how they were going to be building the things in the future or something, lol. Made it easier on me. If you do it, be prepared for a LOT of work, but its so rewarding in the end :thumbsup: Good luck James Link to comment Share on other sites More sharing options...
JeepcoMJ Posted July 29, 2009 Share Posted July 29, 2009 agreed. you CANNOT install a 91+ engine without installing EVERYTHING from the 91+ as for gauges, use the ones from the 94. you will need to either live with the fact that empty is full and full is empty, or get a 1991 to 1992 comanche fuel sending unit (rare) to put in it Link to comment Share on other sites More sharing options...
