Thumbnail Filmstrip of 2017-2019 6.6L L5P Duramax LM2 Can Bus Harness Fish Tuning FTL5PCAN17-19 Images
Unlock the full potential of your tuned 2017-2019 L5P or LM2 Duramax. The Fish Tuning FTL5PCAN17-19 CAN Bus Harness is the essential plug-and-play solution that keeps your truck’s electronics communicating properly after installing a custom tune and emissions delete package.
When you upgrade the DPF, EGR, and DEF system and flash a performance tune, factory sensors and connectors are removed or left disconnected. This breaks the CAN bus network and often causes:
- Check engine lights and stored DTCs
- Limp mode or reduced power
- Tuner communication issues
- Gauges or warning lights acting up
The Fish Tuning FTL5PCAN17-19 provides the correct termination plugs so the ECM sees a complete, properly functioning CAN bus. Your truck runs smoothly with no codes, and your tuner can do its job without interference.
Features:
- True plug-and-play design — No cutting, splicing, or wiring hacks required
- Complete kit engineered specifically for 2017-2019 L5P (uses all plugs) and compatible LM2 applications
- Heavy-duty, OEM-style connectors built for the harsh diesel environment
- Prevents unwanted ECM codes and limp mode after deletes
- Maintains clean dash and proper gauge function
- Works seamlessly with popular tuning platforms (EFI Live, HP Tuners, etc.)
- Professional appearance and long-term reliability
- Made by Fish Tuning — a trusted name in diesel electronics and switching hardware
This is the recommended CAN bus solution by many professional tuners and shops for 2017-2019 L5P trucks.
Installation:
Simple plug-in installation at the factory connector locations (engine bay, passenger-side frame rail, near DEF tank area, and rear passenger wheel well area).
