Factory Honda Camera Wire Indentification

I recently purchased a Factory Clarion Honda Odyssey Backup camera. I would like some help identifying the 4 pin wires so I can hook it up to a my aftermarket HU. My intentions are to solder is up to a Video RCA cable, but need help identifying the which wire is which.

Clarion Camera has 4 wires:
1. Black
2. Green
3. White
4. Yellow

Any help is greatly appreciated.

 

This is pure guess:

White - Power +
Black - Power -
Yellow - Video +
Green - Video -

 

Any other guesses......the more the merrier. Also does anybody know if I need to make a 12v to 6v conversion. I have read that some cameras only require 6v and I'm not sure about his one.......

 

As far as takin 12v to 6v easiest thing 2 do pis buy a 12v universal cig adapter that can b switched 2 6v bestbuy have for round 20 or if u have a newer sat radio cig plug that drops 12v to 5v if u think 5v should b enough

 

Take a voltage meter and check your rca plug end. (assuming that plug comes from the camera) First find the shield which is the outside part of the plug, then the center pin which is the positive. That takes care of the video part then the 2 you have left is power. If one of those is black i would be willing to bet that is the ground then the last one should be your positive for power.

not sure how to tell if its 6 or 12 volts. I would check with 6 first if it doesn't work no harm done its 12. If you try 12 first and its supposed to be 6 you just fried your camera.

 

Just looking at the way the black wire has shrink wrap low, I guessing it is video shield, if you strip back a little you may find out the video +, and then you got 50/50 chance on the two left. But looking green would be the video +, white + and yellow -. You can test it at 6v first to see if you have video and slowly increase it. Or lastly open the camera up and look at the circuit card for hints.
