Locate green w/white stripe wire coming from the APP module (Fig. 1) under dash of vehicle. To confirm that the green/white wire is correct, with engine running and ignition "ON", attach a voltage meter to APP green/white wire. With your foot off the throttle, voltage meter should read .6 volts. As you depress the throttle voltage should increase.
Once you have located the correct APP wire, connect that wire to the white wire coming from the US Gear Calibrator. Ground black wire from calibrator to vehicle. Connect the brown and yellow harness to the D-Celerator main wiring harness D-Feat plug.
