This document is a line-art schematic (exploded/installation illustration) showing the routing and attachment of heater control cables behind the instrument panel, uploaded as applying to a 1978 Ford Bronco. The main drawing depicts the dashboard from behind, with callouts identifying the INSTRUMENT PANEL, HEATER ASSY., and AIR DUCT. Cables are shown running from the heater control head across the back of the dash, with instructions to "ROUTE AS SHOWN" and secure with "TAPE." Two cable attachment points on the heater/plenum assembly are labeled "SEE VIEW A." A lower-left inset shows the heater control face with its levers: a fan lever marked HIGH/OFF, and slider legends reading FAN, COOL, TEMPERATURE, WARM on one row and OFF, HEAT, DEFROST on another. The lower-right inset, labeled VIEW A, details the cable end attachment hardware, identifying the CABLE ASSY., SPRING NUT, and SCREW used to fasten the cable to its bracket. A reader can learn how the heater temperature and function cables are routed, taped, and mechanically secured at the heater assembly, and what hardware (spring nut and screw) retains the cable ends. No part numbers, torque specs, or year/model text appear in the drawing itself.
