I've done the search and there is not much info on this out there. Of course the newer models can do this electronically but what about calibrating the 12v. The one post that came up with any info led me to two transmission sites but the both told me that they didn't sell anything like that. There has got to be a simple way to calibrate the thing. Heck we can do everything else to these trucks how do about this?

Does it have about an inch and a half pulg where the cable goes into the transmission/transfer case?

If so Mopar or a transmission shop has different plastic gears that fit on it and the plug rotates to different positions to match the diameter of the gear. I used to have a gallon can full of them from building autos.
