ears on the Drum. The Transfix Load Arms point in the opposite direction
from the Drum Thermistor. Ensure that the cam followers on the Transfix
Load Arms are under the Transfix Cams.

Sensor harness through the opening in the Exit Module that the other
cables pass through. Seat the Exit Module on the two front locating pins
and then on the rear locating pins.
