Alternator not working after installing back up cam

[Bruno]

I was trying to install a back up cam, jammed a wire from reverse light. After all the wiring the following problems appear,

1. reverse lights don’t work

2. Shift indicator not working 

3. Central doors lock would not unlock when i put to P

4. alternator has zero output( checked by a mechanic, he said usually has low output even it’s dead.

 

Driving is no problem. Transmission still doing right. Anyone know if i has shorted some wiring or just the alternator problem? 
Hoping anyone can help!

Where were you jamming the wire ?

I was trying to use the existing wire which is a 4 pins plug, tested a bit and can't get any video signal and given up using it. 

Finally put a new wiring and have it jammed to one of the reverse light to get 12v power and reverse signal.
