This maybe covered in another thread... if it is I could not find it. On the 12v power in for the Dom's unit the plug mine came with has two black leads off the plug. One has grey writing and the other has grey long dashed lines.

The instructions reference a red wire to 12v and red/black for the. Anyone have an idea which is the 12V and which is ground for my wire?

My camera was not delivered yesterday, so I am just doing half of my planned install today.

Thanks.
