PSI Power 12" Duramax Fuel Injector Pigtail 2-Way Bosch Harness

The 12" Duramax Fuel Injector Pigtail 2-Way Bosch (Gray Keying) Harness is a purpose-built solution for reliable connectivity to Bosch-style injectors found on L5P and L5D Duramax engines. Designed for durability and ease of integration, this harness features a 2-way Bosch EV1-style connector with gray keying to ensure correct fitment and polarity for late-model GM diesel applications. The 12-inch lead offers ample length for flexible routing in tight engine bays, while the opposite end is a blunt-cut pigtail, allowing custom splicing into your vehicle’s existing wiring harness. Ideal for injector replacements, harness repairs, or custom engine builds, this pigtail helps ensure consistent signal delivery to the injector for optimal fuel atomization and engine performance.
