Third Seat Audio (TSA) Control

^ Circuit 8 (terminal A): Variable voltage input from the IM when the headlamp switch is in the PARK or HEAD position. Provides voltage for control illumination at night.
^ Circuit 46 (terminal C): Right rear channel radio audio (+) input from radio. When the RSA is on (and CKT 906 is high) and the TSA is in AUD mode, radio audio is sent to the headphone jacks.
^ Circuit 46 (terminal G): Right rear channel video audio (+) input from the AVM. When the TSA is in VCP mode, video audio is sent to the headphone jacks.
^ Circuit 115 (terminal B): Right rear channel radio audio (-) input from radio. When the RSA is on (and CKT 906 is high) and the TSA is in AUD mode, radio audio is sent to the headphone jacks.
^ Circuit 115 (terminal F): Right rear channel video audio (-) input from the AVM. When the TSA is in VCP mode, video audio is sent to the headphone jacks.
^ Circuit 116 (terminal D): Left rear channel radio audio (-) input from radio. When the RSA is on (and CKT 906 is high) and the TSA is in AUD mode, radio audio is sent to the headphone jacks.
^ Circuit 116 (terminal H): Left rear channel video audio (-) input from the AVM. When the TSA is in VCP mode, video audio is sent to the headphone jacks.
^ Circuit 150 (terminal K): Provides ground for TSA operation.
^ Circuit 199 (terminal E): Left rear channel radio audio (+) input from radio. When the RSA is on (and CKT 906 is high) and the TSA is in AUD mode, radio audio is sent to the headphone jacks.
^ Circuit 906 (terminal L): High with the rear seat audio mode enabled. When high and with the TSA in AUD mode, the TSA connects the headphone jacks to the rear speaker audio radio output.
