    No head lights No marker lights

    Stops and turn signals work

    Plus I have 3 of these (94-97-98) so I would be good to have a good diagram.

    This covers most everything as far as wiring goes for 379's from 7/1994-2000 379's.
    There are some other supplemental diagrams for certain optional things you could get on the trucks but this for sure covers all lighting.
