I am going to be installing a 3 way switch:
Center - Nothing - Screen will show camera in reverse
Up - Video - Screen will show what is connected to the second input
Down - Cam - Screen will show the camera

I don't have the manual for Dom's unit anymore, so i'm wondering which wires are what. Can anyone help on which wire needs to be activated for camera, and which needs to be activated for second input?

 

I know that the BLUE is for the Video 2 (reverse camera) activation... and the RED & Black is for Video 1.... have fun... if you have Dom's unit... he has all the wires labeled very nicely...

 

ok thanks. I installed it earlier this year, but haven't looked at it since and didn't want to open everything and be suprised.

 

I just did mine so I remember it well.

1) Power wire needs to be separated with the +ve going to your 12V source (usually the cigarette lighter)

2) Untwist the blue and white. Blue will go to the backup light to switch to the backup camera.

3) Red/Black wire are the direct wires for the switch.

4) All other wires including these; the green, 2 white, the -ve power wire and a ground wire from Dom's PNP harness can all be crimped together on a ring terminal and grounded at the factory ground near the Nav unit.
