I am trying to tap the connector from my stock satellite box to add an aux stereo wire. I have a 2007 g35 coupe with the stock Sirius unit already installed. I have searched this site and others to try determine which color wires I need to tap for the left and right audio. Please see the pictures below. I tapped the orange/redish with blue stripe and the yellow with blue stripe. I also tapped the black wire for ground. With this setup, I am only getting sound from my right speakers with the SAT source.

 

It's in the sticky at the top -adding AUX or iPod to factory stereo, but here's a direct link:

Yeah I went through that sticky first , but could not find the answer to my question about which wires to tap. I do have sound coming out of my right side speakers with my method. Just need to know which wires to tap for the left side

 

The colors in that post are the colors at the audio unit. There's another harness somewhere between it and the satellite adapter where they change color. I'm not seeing in the manual, at the moment, which wires went to which speaker, but based on their previous correctness, these are the wires at the other harness that they relate to:
The wires at the radio harness (M90) are:
Left+ RED
Left- GREEN
Right+ BLACK
LEFT- WHITE

The wires at the satellite radio harness are:
Left+ Blue/Green
Left- Blue/Yellow
Right+ Orange/Blue
Right- White/Blue

 

Thanks man! That's just what I needed. I'm actually hooking up the belkin Bluetooth aircast to the aux cable.
