$60K and no footwell lights. You gotta love GM.
This is an install post as a follow-up to an old thread with lots of props to heymccall and diesail for their help...

The subject vehicle is the one in my sig - a 2013 GMC Sierra Denali LML.
I got the LED's from http://www.oznium.com/, using the square modules for the footwells and strips for under the running boards. Total cost shipped was $93.71.
Those four squares came as one piece - I cut them apart prior to the picture. I originally intended on using two per side in the front wells, but they were bright enough to get away with one.
The strip lights can be cut every 3 LED's and both sides can be used. I needed to trim two of them to fit where I wanted them under the rear doors, so I ended up using the leftover pieces as rear footwell lights.
The first thing I did was figure out where I was gonna tap into the dome light circuit. Here's the junction block under the driver side dash:
On the right side, second one from the top is connector X-9. See the two grey wires in the #8 position? You want to tap one of them, doesn't matter which.
Note to heymccall - I know you directed me to X-12/5, and I confirmed that with the electrical diagram. For whatever reason, I did not get voltage at that terminal (or X-12/6) with the dome light on. X-9/8 did exactly what I needed.
I grabbed a ground here (X-12/8, fat black wire)
I tested the LED strip with the tapped domelight circuit to see if it dimmed along with the incandescent lamps. It did.
Time to run wire and mount lights. There's a nice big hole in the floor with a nice big grommet in it, just ahead of the driver seat. This is for the shifter cable.
A little WD-40 and the wire pushed right through with the help of a big flat blade screwdriver.
I used 22 guage twisted pair in a teflon sheath - basically plenum rated data cable - running it under the carpet to the door sill, then into the kick panel and up under the dash.
Now that the wiring was under the truck, I split it and ran up the driver side fender well, along the firewall, and down the passenger fender well to get to the other side. I didn't want risk going across the bottom of the truck with all that hot crap under there.
I added a second run from the junction box and under the carpeting to get under the seats to the front seatbacks. By carefully prying at the trim on the seatbacks I was able to tuck the wiring away completely.
Here's a 6-LED segment mounted with 3M tape to the front seatback. Yes, it's wired:
Here's the same segment as seen from the rear floormat:
This is the other side:
Here's the passenger side footwell light mounted to the bottom of the glovebox:
And here's the driver side:
The whole process took me the better part of 6 hours. I soldered and heat shrinked every connection with the exception of the two taps into the harness. It looks and works great, and they're BRIGHT!
Believe it or not I couldn't get a decent picture of the strip lights under the running boards with my crappy Droid X camera. Please watch the video instead:
