1966 Lincoln Continental | Removing EVERYTHING from the Firewall (HVAC, Wiring, Pedals & Heater Box)

Removing the dashboard was only half the battle. In this video, I remove everything attached to the interior side of the firewall on my all-original, numbers matching 1966 Lincoln Continental Coupe. This major teardown is required before I can finally remove the heater and air conditioning evaporator box from the engine bay and continue the OEM-correct engine bay restoration. Along the way, I remove the door sill plates, kick panels, carpet, insulation, HVAC plenum and ductwork, vacuum actuators and vacuum lines, gas pedal, brake pedal assembly, automatic parking brake assembly, speedometer cable, parking brake cable, radio antenna cable, upper and lower wiring harnesses, barrier terminal block, horn relay, and everything else attached to the firewall. This is one of the least documented parts of restoring a 1966 Lincoln Continental, so I wanted to capture the entire process in detail for anyone restoring one of these cars or simply interested in how Ford engineered them. If you're restoring a 1960s Lincoln Continental, tackling a heater core or evaporator core replacement, or planning an engine bay restoration, I hope this walkthrough saves you time and helps you avoid surprises. ▶ Front Bench Seat Removal:    • 1966 Lincoln Continental | Front Bench Sea...   ▶ Tilt Steering Column Removal:    • 1966 Lincoln Continental | Removing the Ti...   ▶ Dashboard Removal:    • 1966 Lincoln Continental | Dashboard Remov...   If you enjoy detailed OEM restorations, please Like, Comment, and Subscribe.
