The CDR model TR-44 uses terminals 1 thru 7 only.  Connect controller 
terminal 1 to rotator terminal 1, 2 to 2,  3 to 3, etc.  There are number 
identifiers for each screw on the terminal strips.  They're small, but they 
are there.

>From the schematic the pin functions are:

1 - Meter to position potentiometer wiper
2 - 14 VDC to position pot
3 - Capacitor to motor winding one
4 - 24 VAC to motor winding one (switched)
5 - 24 VAC to motor winding two (switched)
6 - Capacitor to motor winding two
7 - Return path for AC/DC
