Talk to Rob about a set of cutouts. He has them on his site. These are for the neon but he has ones that will work with our car as well. They are compact and have a small foot print so they fit practically anywhere.

He also has a module I put together that opens and closes them at the flip of a switch so you know they are open or closed regardless of the last state they were in when you turned off the car. It also keeps you from having to hold down a button for 10 seconds to open or close them so you don't run the risk of holding it down to long and over driving the motor when you open or close it.
