Problem. Shift lite inop, Tail id lites inop. Found worn broken wires in the harness that connects the instrument panel to the front electrical box. When the left headlite assembly was installed the harness was pushed and pinched against the air fitting on the front air manifold. Travel vibration caused the harness to wear through the harness wrapping and two wires causing the problem. The broken wires were spliced, the harness rewrapped and repositioned.
