Injector Connector Kit 17- GM L5P Single

The BD Diesel Injector Connector Kit 17-GM L5P Single is a direct-fit fuel injector pigtail connector designed specifically for 2017–2022 GM Duramax and full-size truck platforms. This connector assembly solves a critical integration point in fuel system diagnostics and injector replacement work, where OEM-quality electrical connections are essential to maintain fuel delivery precision and engine stability.

The 8-inch length provides adequate slack for routing and positioning without excess bulk in the engine bay. BD Diesel engineered this connector to match OEM specifications and contact geometry, ensuring reliable signal transmission between the ECU and fuel injectors. Poor or corroded connector contacts are a common source of misfire codes and rough idle conditions on modified and high-mileage Duramax trucks—this kit delivers a fresh termination point to eliminate that failure mode. The single-unit format allows targeted replacement of damaged or worn connectors without replacing the entire harness.

This connector is indispensable for Duramax owners undertaking injector replacement, fuel system upgrades, or electrical troubleshooting on 2017–2022 models. Diesel tuners and engine builders rely on these connectors during custom fuel rail installations and performance fuel system modifications. Any work involving fuel injector removal, replacement, or ECU reprogramming on the L5P platform benefits from having quality replacement connectors on hand.

BD Diesel is recognized for precision fuel system components and electrical harnesses within the Duramax aftermarket community, and this connector reflects that focus on signal integrity and longevity under the demands of turbocharged diesel operation.
