CAN Protection & Diagnostic Plugs | 2017-2019 6.6L Duramax L5P

The DIESELR Signature CAN Plug provides a precision-built interface for the factory CAN bus on 2017–2019 GM 2500/3500 trucks equipped with the 6.6L Duramax L5P. Using OEM-style connectors and pins, it integrates directly into the factory harness without requiring cutting, splicing, or permanent wiring modifications.

Designed for demanding engine-bay conditions, the connector is fully sealed against moisture, heat, and debris. Each unit is manufactured in the USA for consistent fit and finish and is backed by a lifetime warranty.

Gold-Plated & Salt-Spray Tested

Rather than conventional tin or copper contact surfaces, the DIESELR Signature CAN Plug utilizes gold-plated pins for excellent conductivity and long-term corrosion resistance. Gold resists oxidation and tarnishing when exposed to moisture and heat, helping maintain a clean and consistent electrical connection over time.

The connector has also been validated through 1,000 hours of salt-spray testing in accordance with ASTM B117, providing additional confidence in harsh environments where moisture and corrosion can compromise conventional electrical connections.
