Ground wire trouble

[K5Greek]

Hey im new here...been visiting the site for a while and decided to join up.

Anyway on to the question. Im missing a ground wire on my drivers side. Theres no wire in my engine bay and its making my gas and other gauges go crazy. Can someone help?

That missing wired connection almost looks like someone added something and used that spot for a ground, then just cut the wire when the item was removed (like lights), you can just remove that missing wire connector. The other one with the wire IIRC is the ground for the light circuit.

Try running a ground from the back of the block to the firewall. That should ground the body as long as the battery is grounded to the motor (usually grounded to the alternator bracket).

Usually the headlights ground there, as well as a wire to the negative battery terminal. However, the main chassis ground is supposed to be a copper braid (ground strap) from one of the cylinder heads or the block to the firewall. If this is missing or the connections are corroded, all of the body electrical stuff can get screwed up.
