OK, the '06 to '07 cruise servo/module is mounted on an existing black painted steel bracket found on all cars which extends between the front of the battery rack to the left fender. It has threaded bosses on it to mount the servo module. I guess the bracket is discontinued because everyone already has a one on their car. There are two different servos for '06-'07 cars, one is for 2.3L and another for 2.0L. I imagine it is calibrated differently since the motors and throttle bodies are quite different.
The green connector on my '07 car (without cruise) is taped to the harness about 2" away from where it would connect to a cruise control brake position sensor. It's easy to spot.
