Quote, originally posted by ninjapants » exactly, pop out the little coin cup in front of the rear cup holder, remove rear cupholder and it's base (2 parts) and there is a torx screw right there you need to remove. Then you can lift the console up a bit but be careful as it's still attached in the front. Slide in the mounting bracket from the under the console and then bolt it down to the 2 open holes to the right of the e-brake and then the one spot next to the e-brake. Then lower the console back down and bolt the armrest to the bracket and reinstall the 2 trim pieces that go around the armrest base. Screw the console back down and reinstall the rear cupholder and you're good to go. Took me like 5 mins.
I thought there was a wicked easy way to get an arm rest to work with our interiors wit out having to loose the center console and all the glorious cup holders we have with our centers, that rear extendable piece is perfect for fitting a half gallon of tea for long hauls
