Does anyone have a wiring diagram or schematic for a Sigma SG / 3T alarm?
I'm rewiring my 1995 M3 after a cabin fire and this is the last piece of the jigsaw.
Unfortunately not, I've already read this post.
I really need the pinout from the Sigma Sg / 3T alarm module, it's located inside the brass coloured box behind the glovebox.
All the wires from this unit are black so give no indication as to purpose.
