Yes found that that is the digital smb out for a DSP amp. (answering my own question). So on "legacy" tuner modules does the SMB connector provide 12V to the diversity amplifier?

Three relatively easy ways. One, Look on your key, it will have the frequency written on it. Though the text on these keys do wear off fairly easy. Two, Next time you go to the dealership ask your supervisor to check on the frequency. It should be listen on the DCS as an option as to which frequency your key uses. Third, the c-pillar option in which it's written directly on the c-pillar.
