    I have a 72 Skylark convertible that I bought without the dash being installed.
    I have a nice dash bezel with gauges(idiot lights) that I have installed.
    My problems:
    1) My brake light comes on when I turn on the lights.
    2) My fuel gauge reads past full.
    3) My front and back courtesy lights do not work.(new bulbs)
    4)The interior is out of it and there is two black ground wires that are screwed into the rear seat back frame behind the back seat, one of the wires (the one that seems to be coming from the passenger side) is cut, so it is attached to the grounding screw but nothing else. Where should it be attached???

    I checked my ground at the gas tank and it seems good.

    Any other ideas on where I should look for bad grounds etc??
    Thanks

    Here is the pic of the two ground wires connected together. The one that goes to the right, towards drivers side is grounded again, where does the other wire go to it is broken off about 18" from where it is screwed onto the car.
    Thanks

    Chassis manual I have is geared towards a hardtop, not much detail on the convertible.
    There is a ground for the tail lights at the bumper, on on each side of the license plate. The mounting stud for the lense/housing provides a path to the bumper itself.
    I suspect the gas tank ground is one of the two you show behind the rear seat. Can't source the other from the drawings I have.
    The courtesy lights are powered from an orange & white pair starting at the under dash connector, near the fuse box. These are switched via the door switches & the headlight switch. All of these switches are grounded via threads into the door jamb or a jumper from the headlight switch case.
    Your convertible have/had pump motors? Possibly the other ground wire? Also in the area could bo original rear speaker or rear window defogger ground.
