    Generally every wire in IH medium duty trucks is black which makes everything difficult. What trouble are you having?

    Basically dashboard ligths and indicators seem to be failing, but I don´t know exactly what´s going on.

    Use a jumper cable to temporarily add a direct path from the battery negative to the central negative post for the instruments and watch for an increase in brightness.

    On my older IH it was near drivers left shin tucked up under. I bet you have a poor circuit on the ground side.
