Hi there,

Are you talking about the selector not lighting up when installed in truck or plugged into computer for programming?

If you get Hydraflash opened up, on the top menu click "Tools" then "Box/HEX Conversion".

In the new window select your Box Code from the drop down menu. Down a bit, you will see "Recommended Preferred Calibrations". Use this to "HEX code" when selecting tunes for the Hydra. Make sure all tunes are the exact HEX code.

Check out hydrahelp.com for some good info. It mentions the most same stuff I just did, and more.
