This harness set is designed to protect the footwell blowers of the 911 Carrera 3.2 with an inline fuse.

Models from 1984 until April 1986 lacked fusing for the footwell blowers. The fan motors, often prone to failure due to bearing issues, could seize and potentially overheat, leading to damage.

Our inline fuse set offers a direct solution, featuring a 10A inline LED fuse. In the event of a motor short, the fuse will blow and the LED will illuminate, safeguarding your valuable trunk harness.
