1978 Ford Bronco Heater Blower Motor & Ground Location Diagram - Firewall Studs

This document is a line-art illustration from a Ford service manual showing the heater blower motor installation on the engine-compartment side of the firewall (dash panel). Callout labels identify the blower motor, the blower motor ground wire attachment point higher on the firewall, the two heater hoses passing through the firewall to the heater core, and two retaining nuts, one securing the blower motor assembly and another on a stud to the right of the heater hose connections. The drawing shows the blower motor mounted in the heater case with its wiring harness routed along the firewall to the ground point. No part numbers, torque specifications, or year/model applicability text appear on the page. A reader can learn where the blower motor is located, where its ground wire attaches, where the heater hoses enter the firewall, and which nuts/studs retain the components. The scan was uploaded to a 1978 Ford Bronco gallery under the filename 'Heater Studs.gif' as part of a larger set of Bronco service diagrams covering heater, A/C, body, and chassis components.
