I just checked my 38 pin connector. Many of the pins don't have any contacts in them. Here are the 13 that do:

1,2,3,4,6,7,8,13,14,16,17,19,30

1-Ground
2-Voltage, circuit 87 or circuit 15z
3-Voltage, circuit 30
4-LH sequential multiport fuel injection, Engines 104,119
6-Anti-lock brake system, Electronic traction system, Acceleration slip regulation, Electronic stability program
7-Electronic accelerator, Cruise control/idle speed control
8-Base module, Brake assist
13-TNA-signal (gasoline), LH-SFI engines
14-On-off ratio, Engine 119 LH-SFI, Engine 120 LH-SFI (right)
16-Air conditioning, Models 124, 140, 202, 208, 210
17-Distributor ignition, Engines 104, 119, Engine 120 (right)
19-Diagnostic module (USA)
30-Airbag/ETR (SRS)

Of those (excluding 1-3 which are ground and voltages), only 2 have no matching DTC table (13 and 14). Does anyone know those are monitored?

Also interesting is that I don't have a pin in 23 which is supposed to monitor the Anti-Theft Alarm System. Any clues?
