Tools you'll likely need:
* Screwdriver (Phillips or slotted, depending on your car): To remove screws holding the housing in place.
* Socket wrench and sockets (possibly): Some models might use nuts and bolts instead of screws.
* Panel removal tools (optional but recommended): These plastic tools help prevent scratches on the metal when prying.
* A clean rag: To prevent scratching the paint.
Procedure:
1. Prepare the area: Clean the area around the backup light housing to improve visibility and prevent dirt from getting inside.
2. Locate the screws/bolts: The backup light housing is usually held in place by screws or bolts from the inside of the trunk. Open your trunk and locate the housing. You'll need to find the fasteners securing it to the body. These are often located near the edges of the housing.
3. Remove the fasteners: Carefully remove the screws or bolts securing the backup light housing. If they are stubborn, use a penetrating oil to help loosen them before trying to remove them.
4. Gently remove the housing: Once all fasteners are removed, gently pull the backup light housing outwards from the body. It might be slightly snug, so use gentle but firm pressure. Be careful not to force it, as you could damage the housing or surrounding sheet metal. If it's stuck, carefully investigate for any hidden clips or other fasteners.
5. Disconnect the wiring: Once the housing is free, disconnect the electrical connector for the backup lights. This is usually a simple push-and-twist or a simple plug connection.
Important Considerations:
* Rust: 1966 Mustangs are old enough that rust can be a significant issue. If you encounter significant rust, you might need to apply penetrating oil or use other rust-removal techniques before attempting to remove the fasteners. Be prepared for potential breakage.
* Fragile Plastic: The backup light housings themselves can be brittle with age. Handle them carefully to avoid cracks or breakage.
* Repair Manual: A shop manual or online resource specific to your 1966 Mustang will give you the most precise instructions and diagrams to avoid any issues. This is highly recommended.
* Variations: There might be slight variations in the exact process depending on your Mustang's specific trim level or any modifications that might have been made over the years.
If you're uncomfortable performing this task yourself, it's best to take your car to a qualified mechanic. They will have the experience and tools to safely remove the housing without causing damage.
