If you have added a Digital Horsepower PCM to your
2001-2003 Grand Prix GTP you may want this plug and play harness and a factory
GM shift knob with "Performance Shift" button. Using this kit, you can easily
retrofit the knob and harness to give your 2001-2003 Grand Prix GTP the "Performance
Shift" feature of earlier Grand Prix GTPs.
