One plug is for serial communication link and the other is for analog (audio signals). The CD audio level is non-standard and they run as L+/L- and R+ and R- differential signals. Regular Audio is L/R with respect to ground.

The serial link is digital Lexus proprietary standard. Through this plug the central unit switches things in and out and polls what is enabled and does some weird logic as to radio is switched on when say the tape is ejected (example). I would suggest not to mess with this one. And let the system be faked that the CD exists by leaving the original CD player in.

Lot more discussion can be found in aux_in.

Best thing to do is use the Grom adapter. Search this forum for more details.
