1978 Ford Bronco Heater & A/C Control Assembly Diagram - Vacuum Connectors

This document is an exploded-view line drawing of a heater and air conditioning control assembly, showing the control head and its associated switches, cables, and vacuum connections. Labeled components include the three port vacuum selector, three port vacuum connector, air blend door cable, eight port vacuum selector connector, compressor clutch switch, blower switch, and mounting plate. A circular inset ('View D') details the 3-port vacuum connector, identifying the hose/port colors as purple, turquoise, and black, and shows how the male and female halves of the connector mate. The diagram is useful for anyone disassembling or reassembling the HVAC control panel, verifying vacuum hose color routing at the three-port connector, or identifying where the blower switch and compressor clutch switch mount on the control assembly. The document contains no part numbers, torque specifications, or stated year/model applicability; it was uploaded to a 1978 Ford Bronco gallery as part of a larger set of heater/AC reference diagrams. All callout labels are crisp and fully legible.
