Red Devil 1.9 D-Turbo

That wire is an airbag connection, i assume it's for the airbag above the dash, failing that it's probably surplus to requirements. If memory serves the air duct flaps are controlled by cable, not a motor. The 306 doesn't have a pollen filter. Remove that spring with a screwdriver and a bit of ignorance, it's a common issue with clutch pedal issues, there's a guide on it.
