    May have to clean them and try to see the colors. Here's a copy of the wire diagrams for the '79.

    fyi: be aware the 'service interval switch' ties into the oil light wiring.

    The brown/green wire is for the oil pressure sensor switch.

    see if there's anything connected to the ignition distributor (the points capacitor)
