I think this is still a stock post...
My previous 95 XJ Sport, had speedometer / tachometer, oil press, volts, water temp and fuel.
My present XJ SE has no Tach, and a large fuel gauge. Can I swap in a cluster from a Sport to an SE ? Will it be plug and play ? Or will I have to rewire and add Tach wiring ?
Thanks

Wow! There have been a rash of these lately. Cluster swap questions, I mean. It's interesting how particular questions come in.... clusters.....

Anyway....

Yes, it's plug and play. The ECM sends the data to the cluster, and the cluster figures out how to display it.

One thing to note is that your mileage is stored in the cluster, and there is no way to reset it. (Maybe a dealer can?)

You should check with your DMV on the legal requirements for keeping track of the actual miles. There may be some forms to fill out, or maybe you just have to note it on the title if you sell it. Whatever the requirements, you need to be aware of them.

BTW, I have a 94 cluster for sale. See my sig.

x2 - It's just the cluster swap and then you need the gauge type sending units for the temp and oil pressure.
Both sensors just plug right in to the existing wiring and ports. The temp is at the back of the head on the driver's side and the oil is right near the oil filter. I used BSP (IIRC - basically the ones sold at Advance or Pep boys) and they work great.

I did the swap on my 95 and love it. You should get the cluster from Mark as you need a 94-96 IIRC.

Can you take the cluster apart and reset the mileage? I know its illegal and if you can do it will it throw anything off?

You'd have to open the cluster assembly. I've seen posts where folks have done this with varying degrees of success.
I think the biggest risk (aside from the legal stuff) is in breaking the mechanism. If the odometer reading being correct is important to you, I would take the cluster to a speed shop or collision repair shop and let them do the adjustment. That way you're not violating any laws and can be sure that it will be done correctly and function properly going forward.

I personally would just leave it as is (which is what I did). Of course, my title was already an "inaccurate odometer" title since the PO replaced the drive-train. I also don't plan on selling my XJ in any normal sale sort of way, so I guess it's really a personal decision.

A dealer might be able do it if you have the original cluster but the question then would be, will they? Never dealt with this sort of thing before so i have no clue. Just write down the mileage and keep track of it. As far as throwing anything off, the ECU couldnt care less about the mileage.

I just went to my local DOL office to ask about mileage and cluster change... I said my Jeep has 222,221 miles, if I was to change the cluster to one with say 136-165,000 miles is there a disclosure form I need to fill out ?
He said no. He said the State ( Washington) Doesnt care about mileage on a vehicle this old (1994)...When I registered it , I said you want the mileage ? He also said no. They dont care.
He did say, it would be nice to write it down, so when you sell it, you could let the buyer know where mileage was when it was changed....
So there you go...

It's not mechanical. I doubt there's anything you can do by opening it up. Check with the dealer, and again, ask your DMV about the rules. It might be very simple where you live.

It also might be very serious.

I remember Dad had too many miles on a company car so he opened up the cluster and turned back the mileage. In doing so, it caused the speedo to flutter while the car was accelerating... meaning hand went along with the speed the car was doing but it fluctuated up and down at about 5 mph intervals. And when you were at top speed for the speed limit say 45, it would fluctuate from 42 or 43 up to 47 or 48.

You can open them up and turn back the mileage I'm fairly certain up to 96. I know the one in my Comanche I opened up and rolled back when I did the same swap.

Did any of the tabs break when you took it apart? Was it fairly easy to do?

IIRC the Comanche (and early XJs) used a cable type speedometer, I would imagine this might impact how the ODO operates.

No broken tabs here.

Comanches and Cherokees 1990 and earlier were cable. HO were electronic.

apparently this is the correct method for the electronic ones, but don't hold me to it. Do some googling
