    Unhappy Help! Need wiring diagram for my obd2 port

    Hey guys, after weeks and weeks of searching the net and visiting countless mechanics.. I have failed to fix a very simple problem.
    My obd2 port of my Cadillac sts 2005 has been ripped off. Although, the wires are perfectly intact. I bought a female connector but i don't know the wiring diagram for it. *I do have the right diagrams but it's confusing because different cars have the wires differently color coded* so no matter what diagram is available, i need one that is specific to mine. Here are the colored wires that i need help with aligning to each pin. Two wires are still intact but the rest are all ripped off from the obd2.
    Here are the colored wires =
    BLACK
    BLACK AND WHITE
    ORANGE/TAN (ALREADY INTACT TO PIN 14)
    ORANGE/TAN AND BLACK
    GREEN
    RED AND WHITE (ALREADY INTACT TO PIN 16 WHICH IS POWER)

    Re: Help! Need wiring diagram for my obd2 port

    The OBD-II port connector wiring diagram and color code is in a subscription to www.alldatadiy.com - the online GM/Cadillac service manuals plus a lot more.

    I looked in my 2002 version but some of the wiring colors are different from yours.

    Any help here ???

    Try this site. http://www.bbbind.com/tsb-and-wiring...ense-agreement. I have a binder with all wiring for my Cadillacs. Used to be a blind site but now I think they require a name and email. Very helpful site. Good Luck.
