Speedo/Odometre

[MANWHORE]

I've got the speedo unit out of my sII gtst. I'm trying to fit a new speedo in. Would anyone be able to post a picture or tell me exactly what each of the coloured wires do?

I'm trying to fit a digital speedo, therefore i need to solder the speedo as well as odometre.

I've got the speedo working, just don't know which ones are the odometre wire.
