Biotex Posted December 10, 2012 Share Posted December 10, 2012 I was about to purchase a cluster and the sending units that would replace my idiot lights ( i thought), and the seller kindly warned me that they would not be a plug and play swap since my MJ was an 88. I don't mind having to do a little bit of modification or whatever else I need to do, but would like to know ahead of time what I need to do. My understanding is that my speedo is a cable drive, and his cluster is electrical. I'm sure there is a writeup or something on here, but I did not find it in a search. So my question is should I be searching for a set of guages that are specific for the cable speedo, or is there a workaround? Link to comment Share on other sites More sharing options...
Biotex Posted December 10, 2012 Author Share Posted December 10, 2012 Trying hard not to be such a spoon fed newbie, I searched some more and think I found the answer... Is this correct? I need the cluster that is blue on the back vs. white? Years from 87 to 90? FYI: I ended up using the google search with this- site: comancheclub.com upgrade guage cluster jeep comanche Link to comment Share on other sites More sharing options...
64 Cheyenne Posted December 10, 2012 Share Posted December 10, 2012 You need a Renix cluster - pre 91, 91 and up are HO which are electronic. And yes you need an early cluster, and not sure if color differences are a good indicator, but for sure you need one with the mechanical speedo drive.

88whitemanche Posted December 10, 2012 Share Posted December 10, 2012 You are correct on the color its a light blue cluster... i learned first hand after i already spent the money on a electric cluster than a speedo wired gear one Link to comment Share on other sites More sharing options...
xjrev10 Posted December 10, 2012 Share Posted December 10, 2012 If you can find a limited XJ I believe those had the black and red gauges. I've owned 3 89 XJs and one had black and red, the other had blue. Link to comment Share on other sites More sharing options...

relyt120 Posted December 10, 2012 Share Posted December 10, 2012 I believe that the early AMC clusters were also white so color alone might not be the best indicator :thumbsup: ive got a renix 3/4 cluster if you want it Link to comment Share on other sites More sharing options...
