Pins 1, 2 and 3 go to the 500 ohm position pot
with pin 2 being the wiper.  Also pin 3 is
grounded at the rotor.  So my measured resistance
from pin 1 to 3 was 506 ohms.  Pin 1 to 2 was 288
ohms and pin 2 to 3 was 221 ohms with the rotor at
45 degrees at the full CCW position pin 1-2 was
502 ohms and at the CW stop pin 1-2 was 70 ohms.

Pins 4 and 5 go to the motor and with the rotor
not at a mechanical stop the resistance was 12
ohms

Hmmmm. That's exactly the opposite of the schematic I remember seeing online, as well as opposite of their smaller rotator (GXE1000?). Pins 1 and 2 are the motor, 3, 4, and 5 is the position pot.
