Because I'm a f**king idiot

Replacing my broken OBD port, I took a picture of the wiring to know where everything goes and now realize it is not clear enough.

If someone could PLEASE take a look at theirs (E90 LCI, not sure if other E90's will be the same), and let me know the color layout with a picture, I'll PayPal you $25 for the trouble. (the panel comes off with two screws, one holding the hood release, another just below the hood release)

Thanks.
(going to cross-post to the general forum as well, sort of an emergency :-|)

Here's the pic I took:

You can get the pinouts with wire colors from newtis.info

Here's a link to the OBDII plug diagram for my vehicle (2009 E90 335xi):

You can wander around on that site to get the right one for your year/model

Here's a link to the instructions for removing/installing the OBD connector

In case dpaul's excellent info left doubts/questions, here is the TIS OBD II Socket (X19527) circuit diagram for 2008 & 2009 models (including the 2009 328i E90 in Montego Blue ;-)

If you have NO CIC (Car Information Computer), N38b in schematic, then you have NO wires connected to sockets 3, 8, 11, 12, 13. In other words, the diagram you attached is correct, and there are ONLY 6 connected wires: pins 4,5,6,9,14,16. As you probably know, there are TINY pin numbers on the front side of the plastic socket holder. The wire color abbreviations on the TIS schematic are German abbreviations, e.g. GE = Gelb = Yellow.

Thanks George. OBD port all patched up. Info, pics and links saved for future reference which I hope never to need
