I installed one in my 2007. Find the plug for the cable. It is located behind the panel next to the drivers left foot and secured to a channel toward the front of the area. Remove the dummy plug that is installed in the connector. Attach the cable (purchased separately) to the plug and mount the controller. I attached mind on the panel below the dash. There are other locations, but this one was easy.
