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.

Hi Rojie!

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!
