    Default Pinout needed

    I need the pin out for the connector harness to glow plug controller. I need to test #4 glow plug lead. I have changed glow plug twice and controller once and I still get a fault on #4.

    I don't have the service manual for 2006, but it should be a simple matter of checking continuity from the plug stud to the controller connector. I have a 2001 CA model, which is similar to later federal models when it comes to the glow plug system (individual plug monitoring). Post a pic or part number of your controller and I may be able to help with that. Each GP bank has a unique connector into the controller, but they are fairly straight forward.
