e-brake bypass, Alpine iva-d300

1. from the main harness, I just noticed the parking brake wire (yellow/blue) is connected to the orange wire on the black box

2. From the main harness, the foot brake wire (yellow/black) is connected to the yellow wire on the black box.

3. From the main harness, the ground wire (black) is spliced with the black wire on the black box and also has a 3rd wire dangleing.

4. From the main harness, the ignition wire (red) is spliced with the red wire from the black box and also has a 3rd wire dangleing.

5. From the main harness, the remote turn-on wire (blue/white) is spliced with the blue wire from the black box. I dont have the remote so I am assuming I can disreguard?
