Richard, each of the cables requires a 5-prong plug on one end and a five-hole 
socket on the other.  Connect one end of the cable to an amplifier/speaker, and 
the other end to the appropriate socket in the organ.  For a 32C, those sockets 
are on the output chassis mounted vertically inside the bass end of the organ.  
Sockets on the output chassis are labeled as follows:
    Diapason
    Flute
    Main (Swell or mixed)
    Pedal

Assuming you have stock Rodgers cables, the pinouts for plugs and sockets are 
as follows:
    Pin 1 - audio ground (shield)
    Pin 2 - Relay + (red)
    Pin 3 - Relay -  (black)
    Pin 4 - no connection
    Pin 5 - signal (white)
Some technicians reverse the polarity of the relay connections.  This is 
unimportant unless one of the speaker systems has an active crossover that 
derives its operating voltage from the relay lines - not likely in a 32C 
installation.  Make the wiring of the plug agree with that of the socket on 
each cable.

Since you have five amplifiers (and presumably five speaker systems), the organ 
may have an echo (antiphonal) chassis.  If it is a four-channel echo adapter 
(other options were available) all the cables will connect to the echo chassis.

Mixing switches on the output chassis allow the Diapason, Flute and Pedal 
channels to run through their own individual speakers or to be mixed with the 
Swell channel and routed to the Main socket.  Overall volume adjustments for 
the four channels are located on the output chassis.  Other volume and voicing 
parameters are found elsewhere in the organ.

There are no wiring connections to the pedalboard itself.  Each of the wires 
behind the "brown board" is connected to a small glass-enclosed reed switch.  
The end of each pedal lines up with one of these switches and operates it 
magnetically.

Good luck -
B.E.
