OEM backup camera retrofit on a 2007

I am looking for some guidance before I hook up the +12vdc to my OEM camera on my 2007 Tacoma. I am trying to figure out how to wire it into my Pioneer Avic z110bt . There are 4 wires from the camera.

pin 1 white
pin 2 red
pin 3 blue
pin 4 black

Here is my guess

Red = +12vdc
black= 12vdc return
white= video
blue = shield

If anybody would like to help me on this please, Is this correct??? Thanks

 

My 2007 does not have the camera wires under the dash so if any one could help with this. I dont want to fry my camera by hooking up the power to the wrong wires
