That pink line coming from Pin 9 on the DB-9 OBD input and going to the 33920 VBB and the Arduino 9V pin is the 12V line from the car. I don't know what a thumbduino is (maybe a stickduino?), but if you don't have a regulator onboard like the Arduino, that pin on the arduino is the unregulated 12V input going to the 7905 reg. That same 12V presumably is a direct input to the 33290, but I'm still need to look up that part's specs to be sure I hook it all up right, so someone correct me if I'm wrong.
