Rusty, how do you tell the difference between the two black wires or do they both go to earth?  which camera signal goes to pin 5 and  pin 15?

What loom are you using?

I am using the insignia camera with a navi600, the navi600 was installed by Andy at vxmods. I am going to make up my own harness from the camera to the radio.
