Fantastic fan wiring 2010 Winnebago Access

Just bought a 2010 Winnebago Access 31C, and was wanting to install a Fantastic Fan. Just wondering if there is wiring at the existing standard vent (no power) at the front of the motorhome? I know that a wiring diagram is available from Winnebago but just wanted to see if anyone already knew this answer.
Thank you,
Steve
