If your Airbags are not working but everything seems to be plugged in double check the main connector is fully seated.
Brake Light Connector - Many harnesses are equipped with cruise and non cruise options. This 2 pin Brake light connector will be for non cruise models. If the pedal box is a non cruise model it will only have a slot for this 2 pin version of the connector which means the 4 pin model will stay open.
Hazard Connector - Commonly mixed up with the plug going to the steering column. Ensure the Hazard button is with the same harness as the Green connections going to the gauge cluster.
Clutch switch for starter interrupt - This tends to be mixed up with the plug below for the windows. You can identify the clutch switch because the wire gauge is much smaller. The usual color combination is Green with Yellow stripe and straight Black.
Power Window Circuit Breaker - Feeds power to the windows and sunroof. This plug can be identified by the large gauge wire and the common colors of White with Green stripe and Black with White stripe.
Cruise Control Module connector - This many times will stay open, especially for non cruise equipped vehicles. For drive by wire engine swaps, you will remove the cruise module and leave this disconnected.
Data Link Connector - This is an additional port for the Subaru Select Monitor diagnostic computer. It will stay open and unplugged.
Keyless Entry Connector - Either this will tie into the keyless entry unit or if there is no keyless entry there should be a jumper on the two outside bottom wires. If neither exists, a jumper needs to be added to get the door locks working.
Rear Accessory Connector for wagon models - This will stay open for coupe and sedan models and for wagons it'll tie into a cylindrical type relay.
Test Mode Connectors - These will stay open other than for flashing. More on the test mode connectors can be found here.
Initialization Connectors - One or the other of these connectors (not both) will be found on 16 bit ECU models. There is a jumper that is supplied with your tuning software of choice for when the ECU is being flashed.
