some help with trafficmaster, please, read on

hi

have managed to get a s/h trafficmaster unit, same as fitted to
vectra's, but i need the 2 socket wiring diagrams, as there are no
plugs with it, so no colour codes, bit of a long shot i know, the
smaller socket i know is for the button and leds, but the larger one,
well not sure , but realise that it is power and speaker output,

any help would be most welcome.

ps@ i know these are bit gimmicky but would like to have a go at
getting it working,
