Ok, now deal with the HARD part, pulling the console to get under there!

There is a thread here SOMEWHERE that goes all thru the process with photos, etc. I had to get in there in 2009 with my first roadster, have not done it since. Its not a bad job with a manual, but getting that grip off the hand brake can be a PITA.
