Where is the Immobilizer control unit located?

Which of the anti theft system does it leave the pcm to? Referring the orange and brown wire.

Thanks Ken, you have been super supportive. Problem solved. That connector to instrument cluster, I noticed a short on 13 pin, so I had to cut it, then the key light showed with key on run position. Later I reconnected the wire and the light stayed on and kick the car and it started.

The wire I marked in red was shorting, because I ran a continuity with a multimeter and noticed the bit was shorted to ground.

Just as the fault code described

Thanks men
