Generac T1 & T0 new extra wire.

I just purchased and installed a 14kW Generac unit (model 7225 with a Jan 2025 manufacturing date) and it came with the new wiring setup with the NEU connection at the #4 location. I also purchased a generator to ATS wiring bundle from Ziller Electric made specifically for 12kW to 16kW air cooled Generacs that came with a total of nine 18GA control wires, two of which are purple. Since it also included a white w/blue stripe wire I used that for the T1 neutral at #4.

What are the two purple wires for? I assumed they were for the optional battery heating pad which I don't have. Everything else seems to be clearly labeled and color coded at both ends.

I have internet access with whole house WIFI and was able to get an activation code which I had to manually input. So far the unit seems to be functioning properly with the only issue being that I can't get a WIFI signal at the unit. Based on this thread that seems to be a pretty common issue. I don't see that as a show stopper but I have also seen that you can get a different (better?) WIFI antenna that mounts on the back of the unit in place of the factory installed antenna.
