You'll want another renix era cluster. So, I'm thinking anything up to 1990 should work, but hopefully someone else will chime in and confirm.

jimoshel Posted November 22, 2011 Share Posted November 22, 2011 XJ-MJ dash clusters from '86 thru '90 are identical and are direct swaps. The cluster from a a '84 -'85 XJ is also a direct swap but the panel is slightly different in color and gauge shape but the fits the same. You will also have to swap the temp, oil pressure sending units. Link to comment Share on other sites More sharing options...
johnr Posted November 22, 2011 Author Share Posted November 22, 2011 thanks guys the one I'm looking at is out of an 88 xj. what will i need to do to get the tach to work. or is it all ready to go. Link to comment Share on other sites More sharing options...

You will also have to swap the temp, oil pressure sending units. This is not correct. The 84-86 clusters have a speedometer that has the cable attached with a small retaining screw. The tach is not adjustable. The 88-90 cluster has the speedo cable attached to the speedo head with a white nylon pinch connector, and the tachometer has a potentiometer that allows you to calibrate it for use with a 4-cyl or 6-cyl. The early clusters can be used in the later vehicles (and vice-versa), but you have to replace the speedometer cable. Problem is, the question is for an '87 and I don't know which type was used in 1987. The change might even have been mid-year in the 1987 model run.

jimoshel Posted November 23, 2011 Share Posted November 23, 2011 DERN!! Forgot about that Speedo connector. However the panel still fits the hole and by either swapping the speedo head, which will keep the mileage correct, or swapping the cable. Thats what he said. I recently swapped a cluster from a '84, or '85XJ, I don't remember, but it had a 2.8 V6 into a '88 MJ with a 2.5. The tach should have been off reading a couple hundred RPM low. It wasn't. Checked it against a test tach and they were within 5 RPM of each other. Whatever. Link to comment Share on other sites More sharing options...

tugalo Posted December 2, 2011 Share Posted December 2, 2011 For the purists amongst us: there is another difference in the MJ and XJ clusters. The graphics on an MJ are light blue and on an XJ are red. Link to comment Share on other sites More sharing options...

The graphics on an MJ are light blue and on an XJ are red. :clapping: i found another one this one i guess would be from an xj but is a confimed renix with the mechanical speedo. so has anyone ever taken one apart to swap out the odometer? or is there a thread somewhere in here how to?

flint54 Posted December 3, 2011 Share Posted December 3, 2011 Odometers can be very delicate surgery, and they don't normally "swap out", they're integral to the speedometer. They're designed to not be easily altered, to deter fraud. When I got my truck the reset mechanism wasn't working, so I got another speedo, and sent it off, along with proof of vehicle ownership and verified current mileage, to an instrument shop and they reset the new unit to the correct mileage. As I recall it cost me about $60. This was on a 92 electric unit, perhaps the older ones are simpler? Link to comment Share on other sites More sharing options...
Pete M Posted December 3, 2011 Share Posted December 3, 2011 there are writeups on the internet somewhere. :thumbsup: although technically, altering the odo yourself is kinda against the law. you can take it to a repair shop and they should be able to alter it (and give you the proper paperwork). my brain is telling me you might be able to get it done for as low as 20 bucks. doesn't hurt to ask around and see what the rates are in your neck of the woods. :thumbsup: Link to comment Share on other sites More sharing options...
jamonroe75 Posted December 3, 2011 Share Posted December 3, 2011 I just got a gauge cluster for a 1989 jeep comanche Eliminator. What will i have to do to install it in a 1986 comanche? Link to comment Share on other sites More sharing options...

You will need a speedometer cable for an 88-90 XJ or MJ. If the cluster came from a vehicle with a different engine than yours, you may also have to calibrate the tachometer.

If i swap the Speed-o-meter with the current will that be good. You can do that, but the up-scale clusters have speedos with a trip odometer. If you swap in your old speedo, you won't have the trip odometer. It certainly isn't a necessity, but it's nice to have on occasion. Link to comment Share on other sites More sharing options...

johnr Posted December 8, 2011 Author Share Posted December 8, 2011 be careful of the plastic conector at the top of speedo cable. 24 year old plastic is kind of brittle. the hole thing snaped off of the cable sheeth. JB weld to the rescue Link to comment Share on other sites More sharing options...
johnr Posted December 11, 2011 Author Share Posted December 11, 2011 i got the guage cluster installed finaly today the jb weld seemed to work ok. everything works fine but is there a way to calibrate the tack. at idle it reads 200 rpms Link to comment Share on other sites More sharing options...
Eagle Posted December 11, 2011 Share Posted December 11, 2011 Remove the tach from the cluster. On the back, there's a potentiometer with a plastic head that has a "+" shaped recess in it. Turning that adjusts the tach. Hook that up along with a known-good idle tach and calibrate away. Link to comment Share on other sites More sharing options...
johnr Posted December 12, 2011 Author Share Posted December 12, 2011 cool, but I'm confused as to how i can calibrate it with the tach in my hand. or is it a trial and error type thing? Link to comment Share on other sites More sharing options...
Tonynguy Posted June 9, 2021 Share Posted June 9, 2021 don’t know if this was covered but could i swap out each individual gauge? teamcherokee.com has gauges for sale way cheaper than used whole clusters. I have a 87 4.0l automatic with the big fuel gauge and indicator lights Link to comment Share on other sites More sharing options...
