- Summary
- Service Bulletin for Installing a Fog Lamp Backshell. The connector that attaches to the fog lamp is exposed to water spray from the front tires. Even though the connector is sealed, water spray, in addition to wiring that may be pulled sideways, can cause water intrusion into the connector. A backshell can be added to the connector to provide shielding from direct water spray. It also provides strain relief for the wires entering the connector.
