2020-2023 3.0L Duramax LM2 Tuner Harness Plug Kit (GMLM2KIT)

The Shibby Engineering 3.0L Duramax LM2 Tuner Harness Plug Kit provides factory style, weather resistant caps for the compatible electrical connectors left exposed on an LM2 powered truck or SUV running off-road/emissions deleted tuning. The plugs snap onto the existing harness connectors to keep out moisture, dirt and road debris and give the install a clean, factory style look.
