I got a PST-2 with the upper cables and an ODB2 breakout box. No description, so similar problem as you. I found another thread on rennlist.org and have the wiring diagramm for 2000 and 2001 model.
Lower part of your diagramm is the old round 19 pin service connector. I can map that connector to a 16 pin ODB2 as follows
14: TN/ rev counter is pin 9 on odb2
7: L line is pin 15 on odb2
10: GND is pin 4 and 5 on odb2. Has to be connected to both
13: switched +12V is pin 1 on odb2. You can use pin 16 alternatively
15: not used
19: knocking pulse is pin 11 on odb2. Not connected in 2001 model
8: thats the k line, which is the main communication line for the tester. If you connect it to pin 7 on odb2 you can communicate with dme and immobilizer. If you connect to pin 3 you can communicate to all other ECUs. According to the rennlist thread you have to connect to both. Thats makes sense and shouldn't be a problem, but I still have to test!
Good luck
Update: I just tested it. With k line connected to both pin 7 and pin 3 of odb2 i could activate my cruise control including the light in the instrument cluster. Seems to be correct :-)
