I have a 1990 BMW 535i and I just had a Viper 350HV installed in it. The alarm is set up with keless entry to lock and unlock the doors. With BMW's there is also a double locking feature so if you turn the key in the drivers door it 'dead bolts' the doors locked... and if you hold the key in the double locked position for a few seconds all the windows and sunroof will close.
What I'm trying to do is either set the alarm up so that it double locks by default, or assign channel two or three of the remote to do the double lock feature.
The reason I want to do this is so that if I have it double lock by default, when I go to set the alarm I can hold the arm button down and roll up all the windows remotely.
Now I've done a little research and I think double locking is preformed by supplying 12v to the lock and unlock at the same time. There also might be a single wire in the central locking system that does the double lock, and that would be perfect because then I can just connect up channel three to send 12v to that wire.
So is anyone familiar with BMW's and this alarm enough to tell me how to make this work? Is there a single wire that triggers the double locking? And if I could connect it to a seperate channel would holding down the remote button be the same as holding the key in the door at the double lock position?
Thanks

you will need to change the out put on the accessory to validity and connect it to the lock wire (assuming that is the same wire that is conneced to the key cylider in the drivers door) then whenever you hit the accessory button the windows will roll up

Thanks for the reply.
How do I change the output on a channel to validity? Also, I was hoping someone here to tell me where to find the double lock wire that runs from the drivers door lock. (there has to be a wire from the door lock that tells the central locking system that the key's been held, and to activate the rool up)
