Mark R, the physical installation is very easy. Once installed you need to calibrate the unit which is also easy. Basically you compare your dash speedo at 60 MPH against a GPS for actual MPH. You find that difference on a supplied conversion chart that comes with the Speedohealer and input the new calibration factor into the unit and you're done. It doesn' matter what gears or tires you have on the vehicle.

I really liked this article. . . How much did this all cost? Do you think it would work for my '04 WJ on 33s?

Thread revival for the win!

anyways... anybody know if this will work for the geared speedos? I have a gear driven one but I have 2 sets of tires that are different sizes and I like the feature easy adjustment instead of taking my transfer case apart every time. The wiring harness that comes out of mine is identical looking to this (3 wire) but I still have a gear.

I'm not saying we should kill stupid people... Just get rid of all the warning labels...
If you find my comments to "infer" something, they don't. Go to hell.

Great video, this kit will be my next purchase. I recently bought my TJ with 126000 miles on it but I know now it has less than that on it. Previous owner had installed 4.10 gears in front and 4.56 in back with 31.5 tires. Every mile I drive it reads 1.4...
