How to Fix a Hot Wired Car After a Break-in

Last weekend, I returned to my 2005 Ford Focus 1.6 TDCi to find it had been broken into and the ignition wiring had been damaged in a hot-wiring attempt. The would-be thieves were unsuccessful in stealing the car, but they did leave behind a significant amount of damage, including stolen car documents and the radio.

Here is the main damage to the ignition wiring:

Unfortunately, my insurance does not cover vandalism, leaving me to handle the repairs myself. A Ford dealership quoted a substantial 2500 euros for the repair work, citing the main cable spindle replacement at 500 euros alone, and the labor-intensive task of removing the entire dashboard.

Faced with this expensive quote, I’m exploring more affordable options, such as sourcing second-hand parts and attempting a DIY repair or using an independent garage.

My primary question revolves around the feasibility of repairing the damaged cable and connector directly, rather than replacing the entire cable spindle and removing the dashboard. I need to assess if the connector itself is broken and needs replacement.

Is repairing the existing damaged wiring and connector a viable approach? Where can I find a wiring diagram for the connector to understand the connections? What is the technical term for this specific cable and connector to aid in finding parts or information? Are there any unforeseen challenges that might make this repair too complex for a DIY approach with basic tools?

Any insights, advice, or pointers to helpful resources would be greatly appreciated as I navigate this unexpected car repair.
