GM/CHEVY L5P - CAN BUS Plug Kit | 2017-2023

The L5P CAN Bus Plug Kit for 2017–2023 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD with the 6.6L Duramax L5P is required when you remove the DPF (Diesel Particulate Filter) and DEF (Diesel Exhaust Fluid) systems.

These plugs go in place of the NOx and DEF module connectors and provide a closed signal back to the ECM so it reads correctly after the delete. They're made for use with aftermarket exhaust systems or delete pipes and are required for delete tuning on the L5P.

Fitment covers 2017, 2018, 2019, 2020, 2021, 2022, and 2023 Silverado and Sierra 2500/3500HD trucks with the L5P Duramax. One thing to know: if you already bought a full delete kit from The Diesel Dudes, these plugs are included in that bundle — this kit is sold separately for owners who just need the plugs on their own.

Questions about which plug goes where? Call (888) 830-2588 or email sales@thedieseldudes.com and the team will walk you through it.

For off-road/competition use only.
