- Sony Bluetooth Receiver with Android/iPhone/iPod Control, Front USB & Aux (WXGT90BT) [BestBuy]
- Metra Dashboard Adapter (95-7320) [Amazon]
- Metra Stereo Cable Harness (70-5520) [Amazon]
I was initially wary of the dashboard adapter being black, when the rest was clearly... not black. Now I don't even notice. It's not perfect but I have no regrets.
The receiver comes with it's own cable, and you can either choose to snip off the existing connector in the car, or you can buy a car-specific cable harness. I decided I really did not want to jam my hands into the dashboard, stripping and soldering cables in a confined space. I also liked the idea of being able to swap the stock stereo back in later.
Some investigation online, followed by careful testing, yielded the following wire mapping:
|Car Radio Constant 12v+ Wire||Gray||Yellow||Yellow|
|Car Radio Switched 12v+ Wire||Orange/Black||Red||Red|
|Car Radio Ground Wire||Black||Black||Black|
|Car Radio Illumination Wire||Blue||Orange/White||Orange/White|
|Car Stereo Dimmer Wire||White/Black||N/A||N/A|
|Car Stereo Antenna Trigger||Green/Black||Blue/White||Blue/White|
|Car Stereo Amp Trigger Wire||Pink/Black||Blue/White||Blue/White|
|Left Front Speaker Positive Wire (+)||Green||White||White|
|Left Front Speaker Negative Wire (-)||Blue||White/Black||White/Black|
|Right Front Speaker Positive Wire (+)||Gray||Grey||Grey|
|Right Front Speaker Negative Wire (-)||Red/Orange||Grey/Black||Grey/Black|
|Left Rear Speaker Positive Wire (+)||Orange||Green||Green|
|Left Rear Speaker Negative Wire (-)||Pink||Green/Black||Green/Black|
|Right Rear Speaker Positive Wire (+)||White||Violet||Violet|
|Right Rear Speaker Negative Wire (-)||Red||Violet/Black||Violet/Black|
I used some simple terminal blocks to test out my mapping before committing.
Everything worked out, so I went ahead and starting burning myself.
Update: As one kind user pointed out, my original mapping did not connect the Antenna Trigger. This didn't cause noticeable issues with FM reception, but made the AM band useless. I reviewed the stereo wiring guide and added a jumper wire to connect the Antenna Trigger to the Amp Trigger lines and this resolved the issue totally. I notice slightly better FM reception, and now AM reception actually works!
Hope this is useful to someone out there!
