Radio (Outputs)
^ Circuit 46 (connector C2, terminal 18): Right rear channel radio audio output (+). The radio changes the level output between speaker level (when the Rear Seat Audio is oft) and headphone level (when the Rear Seat Audio is on).^ Circuit 115 (connector C2, terminal 17): Right rear channel radio audio output (-). The radio changes the level output between speaker level (when the Rear Seat Audio is oft) and headphone level (when the Rear Seat Audio is on).
^ Circuit 116 (connector C2, terminal 19): Left rear channel radio audio output (-). The radio changes the level output between speaker level (when the Rear Seat Audio is off) and headphone level (when the Rear Seat Audio is on).
^ Circuit 145 (connector C1, terminal 8): High when the radio is on. This signal is used by the RSA which mutes the rear speakers.
^ Circuit 199 (connector C2, terminal 20): Left rear channel radio audio output (+). The radio changes the level output between speaker level (when the Rear Seat Audio is oft) and headphone level (when the Rear Seat Audio is on).
^ Circuit 906 (connector C2, terminal 12): High with the rear seat audio mode enabled. When high, the Rear Seat Audio (RSA), Second Seat Audio (SSA) and Third Seat Audio (TSA) connect the headphone jacks to the rear speaker audio radio output.
