67 Impala no dash or running lights help

Hey guys so I'm new to this site and Google has been failing me so I thought I would try here so I have a 1967 impala base and I have no dash lights or tail lights but I have headlights and break lights I have already cleaned the fuse box and put new fuses in and have 12v going in and out of my fuse I just replaced my headlamp switch and still no change I'm thinking it might be a ground issue but have no idea to the location of the ground this has been driving me up a wall and any help would be greatly appreciated

Welcome to the Team!


There is one more thing to do at the fuse box and that is to separate the two parts. The interior part plugs into the front wiring harness. The front wiring harness is out side of the car cabin behind the drivers side tire and gets lots of water thrown up on it over the years. Between the two cable connections there is ample opportunity to corrode the connections; and over time I am sure they have. Separate them by unscrewing the fasteners and clean it up the bras contacts before reassembling and your problem just may go away.

Is there 12V coming out of the gray wire on the headlight switch? Is the ribbon wire connected to the harness under the dash and in the trunk? Taillights should be grounded through the taillight housings. So if you have brake lights ...that's good. Like Big Dave said look for corrosion on the brass contacts.
I currently don't have a wire diagram in front of me, so if you can wait a few hours, I'll see what I can find.

The gray wire should go to the back of the inst. panel and branch off and go to every where else. Does any of the idiot lights in the inst. panel work? If not, the panel may be unplugged. If you haven't replaced your dash lights, they may be burned out. Also, check your INST PANEL fuse. This is the 4th one down from the top.
The ribbon cable is under the carpet or vinyl on the drivers side and runs from just right of the fuse panel, under the seats, to just behind the trunk partition, then it plugs into the tail light harness.
