I installed a calibration box that I bought from Mike Adams and I think I have the instructions at home and can scan and email them to you later tonight. I'm not sure if yours is the same as mine or if there are any differences but for the most part it has to be the same. Cutting 1 wire from the PCM and attaching it to 2 wires from the calibration box and tapping another wire from the PCM.
