I do not know the answer to your question but a VOM might go a long way in finding the 12V and GND wires in the connector. Honestly, you might consider starting a new thread describing your issue instead of bumping a 7 year old thread.
newtis.info has all the wiring schematics for your X so have a look over there as well.
