If you look at the circuit board and connector, you'll see a black wire going to the board. This is the ground wire. Follow this wire onto the circuit board where it becomes a metal strip (ground plane) running all over the board (it goes to every socket). What you want to do is connect a wire from the ground plane on the board itself directly to the chassis - no connector involved. First, get yourself some STRANDED wire. Don't use solid wire. Stranded wire is made up of a lot of thin wires, and is flexible. Get at least 18 gauge wire, sometimes shown as 18 ga. Heavier wire is better. With wire gauge, LOWER numbers mean heavier (thicker) wire, so 16 is thicker than 18. 14 is about as big as you need but 18 should be fine.
You want to connect the wire directly to the ground on the board. Any place will do. If you have access to a soldering iron, you want to solder the wire onto the metal of the ground on the board. No iron? Then drill a hole in the ground metal on the board. Go to the autoparts/hardware store where you bought the wire, and buy some lugs. These look like a washer (round with a round hole) with a cylinder sticking off from it. Make sure the lug will take the size wire you bought (usually marked on the package) You slip the wire into the thin cylinder, then crimp the crap out of it with a pliers. You can then put a bolt through the lug to electrically and physically attach it to the circuit board ground. Run the other end of the wire (also with a lug) to a ground bolt on the chassis. Keep the wire short. Make it long enough so you can move things around, but don't have 5 feet of wire coiled up. An extra couple of inches won't hurt.
Make sure all of the surfaces are clean and bright before bolting them together. Shine them up with some fine sandpaper, or preferably some Scotchbrite (better because it leaves no grit).
The best is to solder the wire to the circuit board, and then use a lug on the chassis side. It's best to crimp and solder the wire into the chassis side lug. Still no soldering iron? Buy some ELECTRICAL solder. (Not plumbing solder). Wrap it around the crimped lug where the wire is, and hold a lighter under it. It'll flow after a few seconds. Cheap, but it works.
Good luck!
