I'm new to the forum and I'm looking for help on how to install a SpeedoDRD U1 Speedometer Calibrator in a 2001 WJ Grand Cherokee with a 4.0L. Initially, I bought a Banks AutoMind programmer to make the speedometer calibration as easy as possible since it connects directly into the ECM but the programmer could not communicate with the ABS ringtones to make the change for tire size (255x75x17)! The AutoMind programmer is supposed to allow input for tire size and gearing changes to calibrate the speedometer. I contacted Banks customer support and they tried to guide me through the process to no avail! They suggested that I have the ECM 'reflashed' to insure that it was back to stock, which I did, but it not help one bit! Finally, I sent the unit back to Banks for them to look at but they told me that the unit was operating fine and that the problem was with my vehicle. After discussing the problem with them they offered to refund my money, which I accepted. This brought me to the SpeedoDRD. I'm looking for help in finding the location of the correct wires to cut into. In another post someone installed a Truspeed Speed Sensor and gave the following link to locate the wires (http://www.superlift.com/instructions/33002.pdf
) but when I click on the link it says that it can't be found!!! Any help that can be offered will be greatly appreciated!
