    You need to host the pic for it to show. Look at the link at the top of this page for forum hosting.

    Where did the harness come from? There was no connector? They were just cut off?

    Uh oh.

    Go back and look at the schematics I posted and see if there any comonalities between the wire colors there and the wire colors you have.

    See if you can match the colors to these schematics for the PCM. A test light or multimeter can help you verify the circuit. Red connector would be your green one.
