- Check the voltages of the 2x11 audio input control module microfit connector using a multimeter
- Red wire: permanent 12 volts supply
- Black wire: GND
- Blue wire: switched 12 volts
Audio Input Control Module Power Harness - 2x2 Microfit Connector
- Reconnect the retrofit audio input control module power harness
- Check the voltages of the 2x2 audio input control module microfit connector using a multimeter
- Red wire: permanent 12 volts supply
- Black wire: GND
- Purple wire: switched 12 volts
Are the voltage readings correct?
YES: No further action
NO: Replace the audio input control module power harness
