First off, check your laws. It may be illegal to change your odometer in your state.

Now for the How To. I have only found a couple of How To's for the gauge cluster install and odometer recalibration. How ever, the ony ones I have seen are for the XJ's that use an electronic speedometer connection. This How To was done on a 1987 Jeep Cherokee with the 4.0 and Automatic trans, if that matters. For this swap you will need a Gauge cluster to replace your idiot lights, new Temp sensor, and new Oil Pressure sensor. You may also want to disconnect your battery.

Temp sensor: Wells TU108 (from AutoZone) $8.99
Oil pressure sensor: Duralast PS133 (from Autozone) $12.99

First start by getting your cluster, I got mine off of Ebay. You may also want to take a picture of your old and new Odometers for any legal stuff or for your reference.


(I think you can only do the Odometer Recalibration for the Pre '91 gauges, I am using a '90 for my swap because that is what works for my '87)
Start off by removing the 4 screws that hold the clear plastic cover on the cluster, remove the handle on the Trip Reset button (It just slides off) and then remove the cover and colored gauge surround.

Turn the cluster around and remove the two screws holding the speedometer in


Then remove the screw on the front that holds the speedometer in


I found it easier to remove the speedometer if you take one of the screws that held it in from the back, and pushed on it so it would force the speedometer out.


With the speedometer out, turn it around and take a pick of some sort (I used a Hobby Knife with a small blade (watch your eyes). Push it in to the side of the clip on the odometer and pry it out. Be careful, it may go flying.


Now all you do is slide the number wheels over slightly so they spin freely, then put it to the mileage of your vehicle. The 10th's wheel rides on a little click piece. Now put the speedometer back in, but not the gauge surround.


Now go remove your old cluster, there are 4 screws you need to remove




Now pull the dash face off

Watch for this piece, it will fling off


Now locate all of the screws holding the old cluster in, and remove them (there are 6) Also remove the piece next to the cluster. It will either be a clock, or a fake piece to cover up the space (2 screws)


Slide the cluster out far enough to get your hand behind it. Stick it through the side where the clock would go. You will need to remove the speedometer cable, there is a clip on it, press it and it will release.


Now unplut the two large plugs going into the cluster (pay attention to their orientation)



Now make sure you put the light bulbs in the side panel in their correct spots.


Now take the colored surround off of your old cluster and put it on your new cluster, then put it back together.


Put the handle back on the Trip Reset button.


Now put your new gauge cluste back in the way you took it out. Making sure to connect everything back where it went. The speedometer cable may take some fishing to get it back in, since you cant see what you are doing back there.

Now its time to change the sensors out

First is the Oil Pressure sensor, Its on top of the Filter Adapter. Unplug it, and use a 1-1/16 open ended wrench to get it off. I sprayed some AeroKroil on it (you can use PB Blaster or what ever your preference is)



Old and new sensors


Now thread the new sensor in and plug it back up


Now start on the Coolant Temp sensor, Its at the back of the engine. Watch out for hoses like the Map Hoses.


Use a 1/2 inch deep socket to remove it. You will want to put some papertowels around it because some coolant will spill out. Now put the new one in, they look similar, but they are different.


Now re-connect your battery and test the cluster out. Here is a video of mine on start up.

Good write up!
I did the same swap on my 94 a year ago, but I didn't change the odometer(mines exempt in WI cause it's over ten years old). I just remember that I have ~30000 less miles than what it reads.

[FitchVA]

excellent writeup!

[1990JEEPXJ]

thats really low miles for an 87. good write up

[basso4735]

whats up with your temp gauge on startup?

[88XJSport]

Very nice write up. I saw a write up like this on NAXJA, but it is good to have it on Jeepforums as well. And yes.... for the odometer correcting...RENIX ONLY B****ES You are probably the second person i have ever seen (besides me) use the old gauge surround for the cluster replacement. Better than the grey one!!

[jv3kxj]

What year?? I thought the 91+ were impossible due to redesign and they used melted plastic instead of c-clip.....

[jv3kxj]

Oh you were talkin about changing the odometer, I didn't bother with that so I can't say.

[88XJSport]

Ya renix only was meant for the odometer part...my bad

[dajarr]

Excellent write-up!

I tried and tried and tried, but was never able to get that @!!!%&! c-clip off of the odometer to change it, so just I put the original speedo in the new cluster. There was over 100k difference between the two odometers, so just ignoring it wasn't an option. I don't have the benefit of the trip odometer, but that's not a big deal to me anyway.

[88XJSport]

If i lived close to you, i would do it for you. All I did was turn the c-clip towards you so the opening faces you. Next take needle nosed pliers and push on each side downwards until it pops off.
