Links to all products used in this tutorial:
The dash cam (Memory card not included. I've tried 64gb and that didnt work too well although some reviews say it does. Stick to a 32gb memory card):
Micro2 ATR Fuse tap 16 gauge wire w/ 15A fuse:
12V to 5V power inverter mini USB cable: (Also 15 amps is WAYYY too much for powering just a dash cam. So swap it out with the smallest fuse you can find for whatever size fuses you have. For me I used a 5 amp which is still too much but better than 15 amps.)
Dual USB Car Charger for cigarette port to power the tablet:
Final picture first.
Before I had the power to my dash cam just hanging down to the center console and it was powered by the cigarette lighter. It didnt bother me too much and I drove with it like this for a little over a year. When I added the tablet (for off-road navigation), I wanted to power the tablet while the truck was on or off. Currently that cigarette lighter port was only on when the truck was on. On my truck to do that just requires moving a fuse from one spot to another. But that meant that the dash cam was going to always be on, and I didn't want that. So I hardwired it to the instrument panel fuse box located on the passenger side.
Another after pic
I started off using a cable I bought from amazon that converted the traditional 12v power from the fusebox to 5v and 3 amp max. Initially the cable wasnt long enough to get to the fuse box, so I cut off the ends of the existing cable that used the cigarette lighter and soldered that onto this cable. This tutorial isnt to teach you how to solder so I left that part out.
So this inverter was a bit large so I couldnt tuck it into the crevace but it fits just fine between the rear view mirror and the padding on the roof so thats where it stays.
Its relatively simple to get this wire tucked in. This picture here shows the top right corner of the windshield where the roof meets the A-frame. I used a small, but fat flathead screwdriver to carefully tuck it into the interior without scuffing, or scraping anything.
What the cable should look like after its been tucked.
After you've gotten it tucked in behind the plastic, you can start hiding it behind the weather stripping for the door. This is probably the simplest step.
What it looks like under the weather stripping.
Once you've reached the bottom, its time to break it out and back into the cab to get to the fuse box.
For this, you'll need a ground install. I used this 18-22 gauge wire terminator to put on a screw on the frame to hold the carpet/fusebox panel. The screw was just a little bit too large, so I had to cut it open so it could fit around it. You'll see in the next picture.
This is the screw that holds the carpet, and fuse box cover in place. Make sure to sand down any paint because if not, it wont hold a good ground and you'll not get steady power to your dash cam. I also put a washer ontop of this since the screw holding the carpet/fuse box cover doesnt directly push onto this ground. That way it will hold it against the frame better.
I forgot to take a picture of the add-a-circuit fuse tap, but this is it, installed and the ground is hiding behind the back of the carpet. For the 2016 colorado, fuse F29 is only hot when the truck is on. So thats the fuse I tapped into to power my dash cam.
All patched up. You can see the cable coming out of the weather stripping, but thats okay with me.
