Need a VSS in order to make your speedo work. There are a few ways to do this.
#1. Buy a GPS powered speedometer. Then, it never matters what tires or gears you have, it is always the same.

#2. Get ahold of Autometer or Dakota Digital for a speedometer that will work with the rubi case.

I do not think that the YJ speedometer is compatible with VSS...though I may be wrong.

I have a 97 tj and swapped in a rubi case and just spliced the wires into the new speedo sensor. it works, but doesnt show the correct speed. like Maxed Out said you need to get a Dakota digital calibrator or Superlift programmer. I think the dealer can do it for you, so i have heard, for like $50-100. not quite sure. I am wondering if any local mechanic shop could do it? let us know what you plan to do

the speedo is so overrated. thats my opinion. mine don't work as my odometer is dead as well.

I like the idea of the GPS. I want one so bad in my junk, but I see it as fluff. Gears are more important.

Thats just my opinion

depending on the engine, but most fuel injected systems need a vehicle speed sensor. The computer will look for this in its programming and if it doesnt find it, will cause a few issues. Like stalling when you put the clutch in when coming to a stop or slow speed throttle response could be jerky.....

depending on the year of the YJ and motor the pulse on the 241 rock-trac could possibly work. if its a cable style speedo, you may be able swap to the newer gauge if all you want it for is the speedo in the dash.

Crusty, that is correct, but the YJ is a mechanical speedo, so there should be no problem on stalling without a speed-o-meter....

If it is a trail rig, go without...it is just fluff. But if your rig is like mine and driven daily, you kind of need a working and correct speedometer...
