Cluster Swap

[TheDirtyJeep401]

Will an 86 2.5 with Idiot lights swap out with an 89 Comanche 2.5 cluster?

The lights might. I have never tried that. Best bet is to find an 84-86 cluster and swap the entire thing. That is what most people do. If you replace the cluster from "idiot" gauges to full gauges, you'll want a new oil pressure sensor and temp sensor. Since you have "idiot" lights, you have senders which can only signal the "idiot" light to come on.

I may be remembering the years wrong, but I don't think they will. I believe the years that clusters match between are: 84-86, 87-90, 91-95, 96, 97-01. I'm pretty sure the clusters changed between 86 and 89.

Everything will work EXCEPT that the '89 speedometer cable attaches using a plastic clip, where the '86 speedo cable attaches with a metal clip and retaining screw. If you can get the speedo cable that goes with the '89 cluster you should be good to go.

 

Remember that you'll have to swap the oil pressure sender and the coolant temperature sender in the back of the head.

Don't mean to jack the thread but I just bought my MJ a few months back and it's an '86 but has full gauges so PO must have swapped them in. Everything works except temp gauge and voltmeter, I'm going to get the correct temp sender for use with gauges not lights but can someone help with the voltmeter issue, thanks.
