Nice write up but if you had gone down with the wires and ran them through the door sill and then back up to the rear window it would have been WAY easier. That’s the way I did my VIOFO dash cam and you don’t see any wires as they are just pushed behind the headliner.

 

After taking the A pillar off and making sure that the wire going to the rear camera was on the back side of the airbags (which only took about 20 seconds because I had to pull the full length of wire through) it was very easy/quick to run the wire to the rear window. I just followed the door sills, tucked it around the B pillar and then the C pillar. It took about a minute at most I'd say. You can't see the wire's at all, except for where they come out of the headliner and connect to the camera's. I did think about running them through the lower door sills though, but it wouldn't have been any quicker IMO. Either way will work though, and I gotta say, it was much easier than I was expecting.

 

^^ Agree on running topside backwards behind trim and the headliner, instead of the bottom. Didn't even need to remove anything, just tucked it back. Only took a minute, can't see a thing.

 

Just wanted to post a quick line of thanks and gratitude to @67L48 for the post, and also to @chadstickpoindexter for the assistance via PM and thread updates.
I wired mine up the same as Chad with 2 add-a-circuits.
With all the info up-front, it made for an easy task.

I went with the Thinkware q800 pro and will update back after I get some experience with it.

 

I too want to thank 67L48 for his writeup. Made it super easy to wire it up. Not that thiss is by any means a difficult job, it just made it much smoother. For me, feeding the wire down from the A post to the footwell fuse box was one of the easiest parts. Only issue I had is the connector for the constant power. I did connected the plug, made my connections and before I secured all the wires permanently I wanted to test it out. NO POWER, scratched my head for a bit. Got my 12v tester out, traced all my connections. No switched power. Got the plug in that came with the camera and plugged it into the power point and it worked fine. Scratched my head a bit then realized I forgot to plug the connector back in. Cost me about 20 minutes of troubleshooting. Come to find out you have to plug that connector in to get power to the switched hot wire on the other side of the plug...who knew...LOL. All kidding aside your guide really made it go easier.
