Hi all,

I’m based in the U.K. and I’ve just bought a Clifford Concept 650 Alarm and it came along with a Sigma AC29 Central Door Locking Interface.

I plan on fitting this to an ‘03 BMW Touring which needs a negative pulse to lock/unlock the car.

The Clifford uses a positive pulse so the Sigma unit is basically a twin relay kit needed to change from a positive pulse to a negative one.

My issue is there is no wiring diagram with the Sigma unit. So I am on the hunt for a wiring diagram for the (Scorpion, who is now the owner of Sigma) Sigma AC29 Central Dior Locking Interface.

I’ve searched online and have had no luck so far, so I’m hoping some of you guys might be able to help?
