Microswitch, fifth bow latch

WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

There are microswitches at both latches for the fifth bow that sense if the fifth bow is in lock position and ready for locking.

Pin 3 on the left microswitch is connected to control module pin 17 and microswitch pin 2 is connected to grounding point G36.

Pin 3 on the right microswitch is connected to control module pin 32 and microswitch pin 2 is connected to grounding point G36.

When the ignition is turned ON, the control module outputs B+ via a 1 kOhm resistor to the microswitches from pin 17 and 32, and the microswitches close when the fifth bow is locked and the control module inputs are grounded.
