Ah, right, I guess the one you are talking about just cuts fuel and unlocks the doors then?Different inertia switches for the bags Wazzajnr. Early cars had them mounted above crash cans, later were (IIRC) in centre console or might even have been incorporated into ECU.
Addendum: Just read the Electrical Troubleshooting Manual for the 1997 P38....in the Security/Central Locking pages, in the system description it does say the intertia switch unlocks the doors....so I stand corrected....
But it is still on the A pillar none-the-less !!
This post got me out of a heap of trouble as I had a stuck driver's door lock and while trying to free it I trggered the locks with the key still inside. If you want to take the guesswork of working out which wire to ground use a multimeter. Most of the wires will be at ground, one will be at 12V - that's the one to leave well alone. Two other will be at around 6V and one of these will pull up to 12V as you press the tailgate button - that's the one to ground.
Maybe take your postcode out of your post
