I was chasing a wiring problem on my 76 Vette, the rear compartment and glove box lights weren't getting any power, and this is what I found. What looks like an x in the picture is actually a pin hole in the wire that had to be there from the factory. The harness this piece of wire was in runs down the left side of the car under the sill plate and this particular piece was at the forward curvature of the door. It was obviously exposed to water and over time the wire corroded and the wire opened causing a loss of power to aforementioned lights.IMG_5167 (640x427).jpg
