I did that install on my B5 S4. I installed the OEM Sirius Tuner and kept my Phatbox. I think you would need to basically make the same cable that I made.
All that cable that I made does is pass along just the audio signals. But you'll have to run two wires for the CAN H & CAN L. What I did was use some CAT 5 cable and use just two wires inside.
If you want to call me anytime, I'll be happy to talk with you. Email me and we'll exchange numbers.
