The BTR Fuel Injector Inner Harness is engineered as a direct replacement for 2001–2004 Chevy and GMC 6.6L LB7 Duramax engines. Each harness connects two fuel injectors to the outer injector harness connectors, ensuring proper electrical function and reliable injector operation.
Manufactured with precision-molded connectors and high-quality wiring, this harness delivers secure electrical contact and long-lasting durability, even in demanding diesel environments. Four harnesses are required per engine, as each is designed to serve a pair of injectors.
Compatible with both OEM and aftermarket injectors, the BTR inner harness is ideal for repairing damaged or worn injector wiring and restoring optimal engine performance. Cross-references include GM 97207227 and Standard Motor IFH7, making it easy to match with original equipment.
Whether you’re performing routine maintenance or a full injector replacement, this harness ensures a reliable connection and is trusted by diesel technicians and Duramax owners alike.
