I installed mine a few weeks ago. I didn't take the dash apart though. I just used a fiberglass pry tool the same I used to pop the covers off the dome lights to put the led's in. Just put the pry tool underneath the button trim piece at the 2 o'clock and 8 o'clock positions and gently pop it out. Then pull the stock button out unhook the harness, plug the into the GTR button pop it back in and your set. I believe a DIY for that way is on the forum somewhere too
