some help on traffic master 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,
