ok M30 guru's, this black box which is wired into the 101 plug, the car the M30 came from was an auto, is this something to do with that, initially i though it was an alarm or imobiliser (the little light coloured wire looks like a remote aerial). The only connection to the car loom is the wires going to the c101.
Any ideas, any help most appreciated, thanks

if i don't need it i'd happily take it out of circuit.
