Got it but do you know the answer to my question?

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.

I did check with a volt meter and found the right pins.

Now to splice the wires to get access to the right pins.
