PMB Performance, with 20 years of Porsche expertise, is the top 914Rubber retailer, selling more SKUs than anyone. Our nearly two-decade partnership with 914Rubber ensures premium restoration parts. The 914Rubber Headlight Wiring Grommet (Part #99970203115) is a new reproduction for Porsche 356B and 356C models (1960-65), sealing the headlight wiring pass-through to prevent water ingress and wire chafing.

This rubber grommet fits the headlight bucket’s wiring entry, ensuring a watertight seal for the electrical harness. Two grommets are required per car, one per headlight. It’s a direct replacement for the factory part, offering durability and flexibility. For a complete headlight refresh, pair with 914Rubber’s Headlight Adjustment Screw Set (Part #64463111300) or Wiring Harness Components for 356 models.

Installation requires plastic trim tools and a lint-free cloth. Disconnect the battery, remove the headlight assembly, and clean the bucket’s pass-through with isopropyl alcohol. Thread the wiring through the grommet, then press it into the slot until secure. A 356 owner said, “These grommets stopped my headlight leaks—easy fix!” Warm the grommet in hot water for easier fitting, and avoid overstretching.

Our 20-year 914Rubber partnership guarantees quality and support.
