I'm no electrical guru, so be patient please. When hooking up one of the switches (example rear RV camera) I have a red (hot) wire and green (ground). Do I just wire-in the hot to one of the switch wires (probably the 10 amp one violet/green) and connect the ground wherever I can find a good connection for ground, like a screw or bolt in the metal? Is that all their is to it? Thanks

 

Yep that's all there is to it.

 

Here is a picture where I know the upfitter fuse box grounds to.
It is accessable from the drivers side behind the dash.
If you have the flow through console, I think slightly lower than the cup holder area.

 

What camera did you get?

 

jcbuch, Not sure the name, but it has always worked pretty good for the past couple of years. Now that I have a new truck I'm re-installing it. Has a 7" screen and the camera is mounted on the back of my 5vr RV and everything is hard wired.
