Cluster Upgrade

[ComancheFan]

So I have a 1988 MJ Chief with a 4.0 manual 4x4. I found a 1989 Cherokee with a 4x4 manual 4.0 in the junkyard today. I’m wondering what’s involved in doing a cluster swap. The reason I want to is I don’t have a tachometer in my Comanche but I do have gauges. What should I pull off the Cherokee to make it so all the gauges work in my Comanche? Do I need to run a extra wire for the voltage for the tac? Are the sending units different?

Is your truck manual or automatic?

My jeeps manual and so is the Cherokee I will be pulling the cluster from. I currently have the big fuel gauge where the tac is in the cluster I want to swap in.

You just need a phillips head screw driver and your two hands.  Everything else is P-N-P.

 

(Does the XJ have cruise control?  If so, grab as many of the parts as possible: control box, rev counter, upper speed cable, etc.)

I would grab the oil pressure and temp sending unit from the donor vehicle, I had a problem with the temp sending unit on my 88 using an 87 full gauge package.  I even bought a new temp sender from autozone and it did not work but the factory one from the donor vehicle works fine. All the factory wiring is the same so when you plug the new cluster in the tach will work.  I had an issue with the speedo and odometer and ended up resetting the donor vehicle odometer to match my miles.  Also the speed is off but aren't they all.

 

There is a swap over year for the speedo cable from plastic to metal so I would grab the donor vehicle speedo cable too.
