Looking to do some work on my Cobra compact alarm (i.e. the control electronics are built into the siren). It's a 7900 model or something like that, had no luck finding any info but if anyone has a wiring diagram for *any* Cobra alarm I'd be grateful to see it as I reckon some of the wire colours etc might correspond to mine.

PS It has a single 24-pin connector on which 21 pins are used.

Cheers.
