dimming leads are wired to the AO module. The 7-pin receptacle
dimming leads (Pins 4 & 5) are routed to the driver tray but are capped
off enabling a transfer of driver dimming wires from the AO module to
the 7-pin receptacle. These leads must be disconnected from the AO
module and reconnected to the P7 or PR7 receptacle (Pins 4 and 5)
for an adaptive control to function when installed in the
P7/PR7/P7E/PR7E receptacle.
