Hey Layne, thanks for reaching out!
When our good friends at Firestone were out here for a training day I asked what the yellow wire was for on the Firestone Air Command # F39VV and the response I got was that it's for potential future upgrades to the system, but they didn't know what those upgrades might be.
If you can figure out what that magic yellow wire is designed for, then by all means please use it and let me know what you discovered so I can finally get some sleep at night.
