I want to add a 120 mph 93-95 lightning speedo to my 1996 bronco. What do I have to do to get the computer to read 0-120 instead of 0-90 on the speedo? How do I recalibrate that? If I add it how do I get my old milage on it? Any one know how to do this? Ford did it to there lightning bronco.

I think if you just plug in the lightning cluster it will work the way it should. You can not change the milage.
