The back of the middle console just pops right off. Run your fingers under the trim at the carpet and give it a little tug. Despite the look of these being off alignment, I swear they aren't...
Some have asked if there are wires for the RES behind this panel in models w/o RES. I will say there are 2 bunches of wires that are bare and bundled together right behind this panel right at the carpet level. They go under the carpet so I did not trace them out, but they did NOT have any power on them, so I just left them alone.
To remove the console is a bit more involved. You have to pop off the trim at the feet of the drivers and passenger sides next. (You'll notice there are 2 "hooks" at the front so when you go to put it all back, slide that into place first). After removing the 2 trim pieces, remove the 10 mm screws (one each side) that hold the large side pieces of the console down. I also show the ground location I tapped into.
Next, locate and remove the 2 screws under the rubber mat in front of the shifter.
Now you can grab the large bezel around the shifter and remove it by pulling up. There are 2 more screws (one each side) under this trim piece to loosen the large side pieces of the console. You will need to remove the trim directly above the console, this just pops off.
Next the 2 large pieces on the sides of the center console slide out by pulling straight up. They have several hooks so pay attention when you are putting it back together.
Finally remove the 2 10 mm screws under the rubber mat of the center console. You can gain access to the 12 vdc outlet here if that's what you're after. (Note when you put this back together leave the bolts loose until you get the console all snapped back together, otherwise you may not have tight lines onece it all goes back together)
I chose to run a new 12 vdc wire from the fuse box with an add-a-circuit. If you do this it should be the ATM-LP type. I measured 12vdc on the location pictured with ignition on and nothing when off. This location (2nd from bottom right) had no fuse in it, but you can use any location as the add-a-circuit allows you to do this. This also covered over a 20 amp fuse. I chose this over tapping into the 12vdc outlet because I was adding 4 USB charging ports at 2.1amps @5 VDC.
I used the Axxess AX-USBCHARGE 2.1 for my install for a couple of reasons. First they are very basic, no LEDs, they had long leads, and they fit in a shallow location compared to others. See the attached thumbnails showing the depth allowed by installing in this little cubby in the center console. You have probably less than 1" behind it. I actually still cut the back AX-USBCHARGE to allow the cord to bend 90 deg and glued it into place. To test fit I cut a 1" piece of wood and hot glued it into place on the back then reinstalled the trim before making any cuts. Also note the duct directly behind the cubby has a couple of indentations to allow for a little extra depth for installation, so that's why I have the ports mounted where they are, and not at the bottom of the cubby. I assume these indentations were for the components on models w/ RES, where the HDMI and USB ports would have gone. I considered purchasing the plate that the RES uses, but it was rather expensive (Part number 39590-TG7-A11 and it's about $100-$150) and I'm not sure what type of wiring would have to be done. It would then also have an unused HDMI port as well as RCA and headphone plugs.
To get back to the 3rd row, I routed the wire to under the carpet and under the drivers seat hugging the duct that's in the floor. (It's weird, but the duct gets stepped on apparently) Useful to remove the back 2 bolts on the drivers seat so you can get under it easier. The removed the plastic trim under the door and routed the wire there. There's a few pieces including 1 under the picture below.
From here I popped off most of the rear trim. There is a screw under the little handle and a large screw under the tie down that just above the back seat (3rd row) seat cushion. With those removed I was able to get behind it just enough to install the outlet. I used one of the available threaded studs to ground to on the drivers side and grounded to the screw mounted to the "remote tuner" on the passenger side. I removed the 2 screws (bolts) under the seat and folded the rear cushion up to run the power under the seat to the other side.
I opted to install the 3rd row USB between the 2 cup holders on each side. Here's my final install of the 3rd row.
