How do the microswitches in the door lock communicate with the car as I have 7 connections on the lock assembly, 2 pins are the door open switch the other 2 pins in the grey plug don't seem to do anything. I have tested every combination of pins with a meter & can only get a reading from the door open switch not the lock unlock switch in the mechanism or the one on the lock barrel?
You might find the wiring diagram for your model might be of some help - try this link
https://www.scribd.com/document/2878...vo-c70-s70-v70

Page 154 onward (which shows as Page 219 in the 291 page pdf.) has the relevant alarm variant connections.

If your V70 is pre August 1998 you can reprogram pre August 1998 secondhand fobs to your alarm using the method shown at post 10 for the 850
