It's easy, and it takes less that 15 minutes to remove. Unscrew the knee bolster and trim, and you'll find the amplifier above and to the left of the steering column. Its a brushed aluminum box with a long plug on the bottom. It has a bolt and nut, so you may need two wrenches (use 11mm socket/wrench).
The warning buzzer is attached to the CCA bracket as well, so this is your opportuniy to disable that too, if you wish.
ps. I purchased a reman unit from a company in San Diego which I found in Hemmings. $129 for a unit with a three year warranty.
I don't have the company name handy, but you can go to hmn.com and search for cruise control amplifier.
