Our unit was prewired at the rear vent but - it was connected to a load sharing switch to split service between the front bedroom and the garage. I didn’t like that and opted to install a new breaker. The load sharing device was close to service panel so it was a short re-wiring job. There was no thermostat wiring so that was a bit of a challenge to link back to the central unit via the ducting. As Chuck noted the trim ring will reveal all. Likely both 110 ac and 12v dc for a fan is pre-staged. Good luck!
