Connecting Ross-Tech "Ugly cablle" to 1990 200

[Rich Assarabowski]

Can someone tell me how to connect the Ross-Tech "Ugly cable" to the
1990 Audi 200 (which has the 3x2 diagnostic connectors as shown in
http://www.sjmautotechnik.com/VAS5051.htm).  According to Scott Mockry,
only the black and blue connectors are used to connect to the VAG-COM.
The black connector is used for +12V and ground (which would connect to
the red and black pins on the Ugly cable, respectively).

How does the blue and yellow pin on the Ugly cable connect to the brown
connector of the car??
