correcting speedo from what im seeing in the jk the speedo output no longer comes from the t case prb because of the whole (in my opinion) stupid esp thing it apprears the speed is picked up from the wheel sensors the service manual doesnt do a good job on the output connector location so being said since the wheel sensors are using some sort of output voltage for speed input could we not make some sort of voltage regulator to correct for tire size like somthing like the superlift module
