@olivertwist , did that Puerto Rico LC have rear heat and AC. I see the fan button on the lower panel. I just have to ask.
I'm tracking down 2 unknown wires, a voilet and a blue/black next to eachother in the A45 plug. This 2006 doesn't have those, nor are they in the wiring book or FSM, NAV or non NAV.
edit, those two are in your a45 plug but not in mine, nor in the books.
edit,,,, nevermind I found it. Seems like all I have to do is.... post a question and then pay money to some site for the real EWD.
For the real wiring diagram you need TIS downloads.
