I know this is an old thread but thank you.I know this thread is really old, but It helped me work an issue I had on my mustang. I wanted to add that to change the switch out of the door latch assembly you there is a plastic tab you have to push in to rotate the door sensor 90 degrees. If you hold the new switch in position and look where the key tooth is pointing you can easily see the tab you have to push in. Once you push it in, rotate the sensor and it will pull straight out.
