I concur with Dale's description.
G2800DXA model (with Cinch connector on control box) - Also the same for the
G1000DXA model.
1,2,3 are for the potentiometer
4,5 are the motor and 6 relates to the stops.
I am happy to scan and supply the schematic.
Also note: I have found their version control is very poor. Moving from Cinch
connectors to Molex; FT1000D - always send the original manual when having it
repaired as these radios had changes that were not well documented (but I
digress). Regards, Mark, K1RX

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.
