Product Details
Premium Shibby Engineering Harness Plug Kits
DPF/DEF Electrical Connector Cap Kit
These Shibby Engineering plug kits are designed to cap and seal unused factory electrical connectors that may remain on the vehicle harness after DPF/DEF system-related modifications. The purpose is to protect the OEM connectors from water, mud, road salt, dust, and corrosion, while keeping the harness looking clean and “finished” instead of leaving open connectors exposed.
What this kit does
-
Caps/seals unused OEM connectors related to DPF/DEF systems
-
Helps protect terminals from corrosion and contamination
-
Provides a cleaner, more professional harness finish
-
No cutting or splicing required — connector caps are matched to specific factory plugs
