2001 EJ22 into a 2003 Legacy

Didn't catch before that this thread is 4 months old.

 

I checked the FSM on those connectors.

The small grey 2 pin is for the backup light switch.

The brown 2 pin next to it is the Nuetral position switch on the trans. Those are normally attached to the same bracket as the other connectors on the bellhousing. The harness for those runs across and down the left side of the trans to the switches at the rear of the trans.

 

The large grey 6 pin connector is for the front O2 sensor.

The grey 3 pin connector is for the speed sensor on the trans.

These are also normally attached to or near the bracket on the bellhousing.

 

There is also a connector for the rear o2 sensor somewhere in that area. Its grey with 4 pins. There is an extension harness for the sensor that runs down the side of the trans in the same place as the wiring for the 2 switches. It should have white plugs on the ends.
