Ok, first things first. I know this is not going to be a pretty install, its more about the components than the wiring, but it is cheap, easy and best of all it works. Around $50 ($85ish) if you buy the Daystar GPS holder like I did)
How I got here. I bought an aftermarket head unit and had mixed feelings on it. I ended up using all of the Bluetooth stuff through uConnect and I was going to end up using it mainly for the GPS and backup camera. When the backup camera didn't work, and I got the run around from Crutchfield for 2 days, I ended up sending the head unit back. I still wanted a backup camera though. Somewhere in between I broke the Video cable so when testing this setup, I decided NOT to run everything neat and tidy - I can do that later.

I know this is very basic. But if I can do it, you can. I had never soldered wires before, so it was all new for me. I would try to explain how to actually do the steps but since it was all new for me, I will leave that to the experts - you can hit youtube easy enough for the wire connections and such.
I started off soldering the 12v accessory plug to the power connection for the LCD. Simple. Black with white stripe to red and black to black. Then I hit it with the shrink covering and used a lighter to make shrink it down. Remember these are push in power connections that plug in where you connect the video cable, so you are not directly connecting anything at this point.
I then did the exact same steps to the power connection for the camera itself. Once I had these ready. I started the actual install.
I moved fuse M7 so that I have power to my rear 12v only when in acc or run mode. More info here:
Is the rear power outlet a switched source?
This helps by letting me keep the camera plugged in all the time but puts no drain on the battery. I did this so i could also use the backup camera to help with blind spots. I figured it couldn't hurt to have extra vision now could it?
Easy enough right? Now here comes the hard parts.
I installed the lcd into the Daystar phone/gps holder:
Now I plugged the power cable into the red power connection for the LCD. I also connected the yellow RCA plug into the yellow connector for the LCD. I then let the cables hang down the side of the dash (like I said down and dirty for now). Plug in the 12v into your 12v outlet (which is also power only under acc or run).
See? Really difficult, I know.
Now I ran the cable next to the center console and out the back. I stuffed it under the carpet I keep my rear seat out) and brought it over to where the subwoofer and 12v outlet are in the back.
Now I fed the RCA cable through the tiedown hook as well as the power cable for the RCA camera through that hook Plug in that 12v adapter now. Open you rear cubby. Pull out the plastic cover. See that little plug at the bottom? Pull it out. Feed your RCA and power cables through there. I kept my extra cable here for the time being.
OK now here comes the part everyone does differently. I wanted something east to move and replace as if it had never been there (also why I used the 2 $2.77 12v adapters). I mounted my camera on a plastic hitch cover I already had.
I ran the wires for the camera through the back of the hitch carrier, plugged them into the cables I just dropped. Tied everything up so nothing was hitting the ground. and there you have it.
Cheap (under $50 if you dont buy the extras I did) easy (no tearing apart dashes or panels) and best of all it works. I can change the camera if this one breaks ( or mount differently if I decide to) because this was all down and dirty, quick and easy with no permanent changes to your Jeep !
