[V8] DTC Scanner

[S_Matus]

I just purchased the latest Ross-Tech scanner the Hex-USB+CAN and I also have the 4x4 adaptor for non ODB-II cars (like the V8). I need this scanner to also work on the wife's allroad.
 
I pulled up the carpet on #3 and saw an array of 4 connectors.  Each end of the 4x4 connector is indexed to only work on the corresponding connector.  The first onboard connector is power is unique and other 3 connectors are of the same style connector. 
 
How is the scanner used?
 
Do I mate the power connector and then test each of the 3 connectors individually?  Can I access multiple control modules with one connector? Or is each connector specific to a particular control module?
 
Does anyone have experince with the Ross-Tech scanner that can share your experinces using this device?  I want to hold a troubleshooting session this weekend (Ed K.!)
 
Thanks,
Scott.
