Hello, thanks for posting

I'll have to take a look at the wire diagram and possibly give you a link for an illustration, this is going to take a little time, I'll get back to you very soon.

Please copy this link into your browser for a copy of the factory f/p diagram. You will see some wires designated colors as W/L this means white and light blue. Let me know if you have any questions.
