Dash Pad Covers

That's a nice interior. I always like a clean A body interior. does everything in the dash work? i am working mine now.i want everyting to work. I found outt hat the ammeter in my ralley dash, if those wires are unbolted ,the car wont run. its like the main power feed to to the car LOL!.
Radio doesn't work. The speaker is shot for sure. I disconnected the ammeter (just bypassed by bolting the 2 wires together on the post)
