This is very easy can't do this, then I don't know what to tell you!
I order my GTR push button from amazon for $36 with 1 day free shipping.
And now on to the install
1st: you need a small flat heads and your driver linsence.
Next you take your driver linsence and very easy and lightly put it behind the sliver ring and slide it around it and there is too clips that need to be pop out. You can do it fast and rough but your most likey damage or break it !
Next ounce you get that ring off use the small flat heads and push the little brown clip out of the push start button. Then slide the sliver ring off.
Next instal the ring on the GTR button and clip the plug in. But make sure the sliver ring goes on the right way there a little gap/indent so it can be held in place. You will figure it out because it won't sit right!
Next plug the brown clip in the GTR button press so it goes on acc on & then off to make sure the light and it works like it should!
Then push it into the plastic part of the car make sure it firmly in place and here both clips pop in place!

This write up was done with my iPhone 4 sorry it could have been better! And this install took less then 5mins and it was my first time doing this! And it will take me 2mins tops now really really easy!
