I'm tracking down a power issue with my radio and Bluetooth modules and at a loss on locating the Dashboard/Rear Coupling (D020) in the engine compartment. The radio and Bluetooth are not getting power and I thought power was distributed through the Body Control Module (M001) E-12 (+30) and E-4 (+15) for the radio and E-5 (+15) and E-19 (+30) to the Bluetooth via the D020 Dashboard/Rear coupling. However, none of those pins have wires going to them only pin 20 for the Diagnostic Socket. Can someone tell me how the radio and Bluetooth get power and if it’s through the D020 a picture of where that’s located would be helpful? Thank you.
