The hidden coax possibly goes to the eject box for the antenna coupler. You'll have to follow it back up the car to see really.

The TCU has two GSM connections, to allow the assist to steal the connection to the roof antenna for emergency calls.



You might be able to rewire the 54 pin connector. Someone else will be able to tell you for sure. Since you have a BITII 54pn to 54pin adaptor, you may have the TCU pinout on the connector on the main harness. Peel back the fabric tape and check the pinout. You may find it's plug and play.
