Ground for instrument panel?

[dan42]

Does anyone have a picture of where the ground goes for the instrument panel lights? I have the diagrams, but they are hard for me to interpret. I have changed the bulbs, the printed circuit board, the headlight switch, and the fuse (all brand new), and nothing has worked so far. The condition of the wiring looks O.K., so I suspect a ground wire, but I don't know where to look. A picture from under the dash of what it's suppose to look like would help me to see if there's a missing ground. Thanks in advance.
