Jacob Ochs Posted May 22, 2014 Share Posted May 22, 2014 I want to do a full gauge cluster swap I my 86 Comanche 2.8l could I get any full gauge cluster from a Cherokee as long as it has the spedo cable? Link to comment Share on other sites More sharing options...
Eagle Posted May 22, 2014 Share Posted May 22, 2014 No. Speedo cables are not all the same, Jeep changed the design in either '87 or '88. Ideally, you need a cluster from a 1984 thru 1986 XJ or MJ -- 1987 will work if the cable attaches to the speedo head with a metal clip and a screw, not a white nylon push-on connector. You can use the '88 - '90 style if you get the speedo cable along with the cluster. If you get the older style cluster, it MUST be from a 6-cylinder vehicle. The older ones did not have a calibration potentiometer on the tachometer, so a 4-cylinder cluster will be WAY off on the tach reading. The '88 - '90 clusters had a potentiometer on the tach, so it could be set for 4-cyl or 6-cyl operation. Link to comment Share on other sites More sharing options...

That sounds really confusing and hard to find as well Link to comment Share on other sites More sharing options...

Why would you want to do that when a factory cluster is just a junkyard (or a phone call) away? Link to comment Share on other sites More sharing options...
Jacob Ochs Posted May 22, 2014 Author Share Posted May 22, 2014 I guess your right, junkyards around here tend to screw you for that, who would I call? Link to comment Share on other sites More sharing options...

Or post a Wanted ad in the Clasified section. Actually think I may have one in my parts collection. Know several others have them also. Link to comment Share on other sites More sharing options...

oldseddie Posted May 22, 2014 Share Posted May 22, 2014 Probably have an 87 full cluster available if it would work. PM me if interested. Link to comment Share on other sites More sharing options...

Dillithium Posted May 22, 2014 Share Posted May 22, 2014 My 86 2.5 had a metal clip to hold the speedocable in, my donor cluster did not, it had the white nylon fitting. I swapped over the metal clip to the new cluster to make it work. Link to comment Share on other sites More sharing options...
Jacob Ochs Posted May 22, 2014 Author Share Posted May 22, 2014 Did the tachometer work? Link to comment Share on other sites More sharing options...
Dillithium Posted May 23, 2014 Share Posted May 23, 2014 Worked fine, but I still need to adjust it. It's not accurate for my 2.5 Link to comment Share on other sites More sharing options...
