I searched but came up short, I just installed the PA11-NIS to my factory bose system in my 03 Z and now the Service Engine Soon light is on? Any thoughts?

 

Did you disconnect the battery before pulling the console out and unplugging any connectors (gauge pod, A/C controls, etc)? If not, that can trigger the CEL. Disconnect your battery then step on the brake pedal for a few seconds to drain the stored power to the ECU. Reconnect and the CEL should be gone. If not, better take it to Autozone to get the code read.
