They are built inside the lock unit. They are hall sensors detecting the latch position. The position sensor on my driver's door failed and started to randomly turn on the alarm. Also sometimes while driving showing "DOOR OPEN" on instrument cluster. I took the lock unit apart and there was nothing obviously wrong with the sensor. Eventually installed a new lock unit.
