I just wanted to say a big THANK YOU for sharing. After looking around at other options I decided to just duplicate what you did. I bought the exact same stuff you chose! I used a piece of 1/2" flex conduit to run the wire to the rear, and I added the wires for my rear LED pods in the same conduit. I mounted the camera on the bottom of the tailgate. Up front I cut the camera wire so I could thread it through the little hole where the rivet for the warning sign on the center of the dash used to be. Then I soldered the wires back together where the joint is protected high up under the dash. This also allowed me to shorten that cable rather than wad it up. I put the camera on a toggle switch so I can turn it on and off. It's too bright to use all the time (at night).
At first I thought this was just a whistle and bell, but its very practical. It's impossible to see directly behind these things no matter how many mirrors you have. I find myself using the camera several times per ride. I installed this a couple of months ago and I have been meaning to tell you how much I appreciated your post. Thanks again!
I'm planning to purchase the same Ram mount for my iPhone. I'll put my iPhone where the camera monitor is now, and move the camera monitor to the right in the new mount.
