Please check your connector and PCM before ordering!

The 1998 vehicles are a split year and may have the "older" PCM style, which will NOT work with our Orion Reflash System. That PCM would use a specialty Hydra Chip. Give us a call for details on the 1994-1998 vehicles. Check the gallery for PCM references.  

The Orion Reflash System requires a Windows laptop!
