I have a PC3 USB "older style" that I will sell for $100. It has no Software but, you can download it from Dynojet which is fine. It uses the grey wire and T-tap so you will have to buy a new T-tap from AutoZone for about $2.00 if that! I do not have the 9v adaptor or the supplied USB cable. Any USB cable at homewill do and many websites sell the 9v adaptor for $10.00. This is just the commander with a stock Warrior map. You can do the PC3 perfect install that was deveopedREDHORSE that makes the PC3 work even better (digital grounding). Again the map that is on there is for a stock warrior.
