Description
Description
The 2024 Duramax L5P DEF Module Diagnostic Plug is built for precise communication with the updated DEF control system found on 2024 GM 2500/3500 trucks. Made in the USA using OEM connectors and OEM terminals, this plug integrates cleanly with the factory harness for accurate data transfer during diagnostic or service work.
Every connector is 100% sealed, protecting the terminals from moisture, dust, corrosion, and harsh under-hood conditions. This ensures a stable signal path for diagnostic tools and CAN-based equipment that interface with the DEF module.
This plug is ideal for technicians or truck owners who need a dependable, professional-grade connector for DEF module communication on 2024-only L5P platforms.
Indexing Tab Fitment Note (Important)
The 2024 DEF module harness includes two factory indexing tabs that prevent aftermarket plugs from seating fully. These tabs must be trimmed for proper fitment.
Many technicians use a die grinder, small cutoff wheel, or similar tool to remove the tabs cleanly.
(See product images for the exact tab locations.)
This adjustment is quick and straightforward, but the connector must be fully seated for proper operation.
