Unlock the full potential of your 2024+ L5P Duramax with the Fish Tuning FTL5PCAN2024 CAN Bus Harness. This precision-engineered harness is the critical link that keeps your truck’s sophisticated CAN Bus network fully functional when performing custom tuning, emissions upgrades (EGR, DPF, DEF/SCR), or other performance modifications.

On the latest L5P platforms, upgrading the factory NOx sensors and DEF control modules disrupts CAN communication. Without the proper interface, you risk check engine lights, limp mode, communication errors with your tuner, or limited tuning capability. The FTL5PCAN2024 harness solves this by providing exact-fit plugs that maintain proper CAN line termination and ECU communication, exactly what professional tuners and builders rely on.

Features:

• 2024+ L5P Specific Design — Updated connectors and pin configuration for the newest Duramax electronics.
• Complete CAN Bus Solution — Includes the required plugs for NOx sensor locations and the DEF module connector to keep the entire network online.
• OEM-Matched Quality — Precision thin terminals and robust construction that replicate factory harness specs for reliable, long-term performance.
• Tuning Essential — Enables full communication with HP Tuners, EFI Live, and other platforms so you can safely unlock power, torque, and efficiency gains.
• Eliminates Common Problems — Prevents CAN-related DTCs, limp mode, and drivability issues caused by missing factory modules.
• Plug-and-Play Installation — Direct replacement at the factory locations (professional installation strongly recommended).
• Fish Tuning Quality — Built by the diesel performance specialists trusted by serious L5P builders.
