i bought a 79 elco, and there was a lot to do. I'm close to completing it, but there is a yellow wire underdash in harness that is smoked, connecting to fuse panel at the "acc" labeling? not sure what it is, but would rather fix it, then have to tear dash up again. I noticed it runs in the harness that goes over and across the instrument cluster, but it seems to keep going and im not sure where to look, because the cigarrette lighter wires have been spliced in somewhere else, but nothing else looks burnt. I have checked wiring diagrams, but no ideas there either...any help I can get is greatly appreciated.
