One (1) wiring harness is supplied to connect the ESC2020 Controller to the Auxiliary
Control/Status (AUXCS) Option Board.
A 16-position connector, J1, as well as a 3-position connector, J2, are mounted onto the
AUXCS circuit board. J1 controls the status and control functions available in the AUXCS
board. J2 controls the PA/audio functions. The single harness comes out of the ESC2020
Controller with an 18-position connector, J11. All of the available functions of the AUXCS
board are addressed through this one single harness.
