Got this camera for a good price> As you can imagine I want to install it. Well as you can see below the instructions are sketchy. There are two wires that plug into the camera and the display. Both have a power connector on one end and the other is a pair of wires Black and Red. I'm guessing on the display end black to ground and red to power switched or not?? On the camera end I figure black to ground and red to reverse lights. Have I got this figured right? Went to their site and no install directions available.
