Body wiring grommet with relay holder. This fits under the left of the seat and relocates the relay as part of a retro-fitted "safety loom" to inside the C5 instead of leaving it cable-tied to the chassis exposed to the elements.

This is a replica part that I have designed and produced to be as close to fit in the original space and be non-destructive. This has holes for routing cables as far away from the wheel as possible. The relay holder relocates the safety loom relay to a better position requiring less wiring. There are two small holes which can be used for fitting a horn to the grommet instead of drilling holes in your C5.

This is 3D printed in flexible TPU filament. Relay pictured is not included.
