djag12 Posted March 19, 2008 Share Posted March 19, 2008 My current cluster has full gages except for tach (has large fuel gauge that every one of my friends make fun of) if I change it to a tach cluster what do I need to do to get tach working? Is the cable there and it's plug and play or do I need to run new cable? Link to comment Share on other sites More sharing options...
jaekl Posted March 19, 2008 Share Posted March 19, 2008 It'splug and play. Just make sure it from correct generation of cluster. Early speedo cable type, late speedo cable type (sometime in 87) or later electrical speedo, Link to comment Share on other sites More sharing options...
500 MJ Posted March 19, 2008 Share Posted March 19, 2008 You also need to swap coolant temp and oil pressure sending units, otherwise it won't read correctly... They are really easy to get to, oil pressure is by the oil filter, only one wire goes to it and the coolant temp is on the head, way back by the firewall on the drivers side. Again, only one wire to that one... If you grab the cluster from the yard, get the sending units too, they can be costly... Link to comment Share on other sites More sharing options...
skimore11 Posted March 19, 2008 Share Posted March 19, 2008 I didn't know there was a gauge cluster with oil and temp but no Tach. If that is what you have it should be a direct replacement. I didn't have the temp and oil so I needed the sending units for those. Link to comment Share on other sites More sharing options...

It should be a direct swap only needing to be sure that it is a cluster from an '87 - '90 application. Link to comment Share on other sites More sharing options...

Â he's got full gauges minus tach. Â it's plug and play, get one from a 88-90 renix. Link to comment Share on other sites More sharing options...
djag12 Posted March 19, 2008 Author Share Posted March 19, 2008 Here is a pic of cluster Image Not Found Link to comment Share on other sites More sharing options...
djag12 Posted March 19, 2008 Author Share Posted March 19, 2008 oh, by the way the truck was off when I took the pic should all the gauges lay flat? Link to comment Share on other sites More sharing options...
88XJSport Posted March 20, 2008 Share Posted March 20, 2008 I wish the gauges did "die to the left" when the truck was shut off (like the volts gauge) but they don't. And it drives me nuts... Â But their is one problem.....59 THOUSAND MILES!!!!!! Â Â Â Â Lucky man. Â Â Link to comment Share on other sites More sharing options...
djag12 Posted March 20, 2008 Author Share Posted March 20, 2008 Ya, I found a northern truck with very little rust (all small surface rust) but floors need replacement with 59,000 miles. Carfax showed milage to be correct. That's why I think I may want to change out the speedo if it is possible into the new cluster. I still haven't put pictures up so maybe this weekend Link to comment Share on other sites More sharing options...
JeepcoMJ Posted March 20, 2008 Share Posted March 20, 2008 you MUST get a cluster that's within 1 year + or - then. make sure it's got a trip meter just in case, and then your speedo bolts right in. Â matter of fact, let me check my clusters...i may have a cluster minus the voltmeter or something, but has the tach. Link to comment Share on other sites More sharing options...
500 MJ Posted March 20, 2008 Share Posted March 20, 2008 I stand corrected. Never seen one with full guages minus the tach... Link to comment Share on other sites More sharing options...
jaekl Posted March 20, 2008 Share Posted March 20, 2008 The 5/6 gauge cluster was standard on most XJ's except the base with just fuel gauge. On MJ only the top levels had some gauges as standard but was optional on the lower packages. Whereas the XJ base did not have any optional gauges. So it was in 86. The tach then was an additional option. Link to comment Share on other sites More sharing options...
djag12 Posted March 20, 2008 Author Share Posted March 20, 2008 I think this must have been the only option the truck had except for maybe a radio (if that was an option). JeepcoMJ let me know what you find in your 'cluster stash' Link to comment Share on other sites More sharing options...
brigarpeon Posted March 20, 2008 Share Posted March 20, 2008 What will you use for a fuel gauge then? Link to comment Share on other sites More sharing options...
djag12 Posted March 20, 2008 Author Share Posted March 20, 2008 Hopefully the new cluster will have that gauge or someone has a spare one for sale Link to comment Share on other sites More sharing options...
88XJSport Posted March 21, 2008 Share Posted March 21, 2008 From what I recall, the Full gauges minus tach was equipped on Pioneer XJ's and MJ's. The tach was opitonal, but most didnt fork the cash for it. Link to comment Share on other sites More sharing options...
