Elite 2500 GM GEN IV LSx (LS2/LS3 etc) DBW Ready Terminated Harness Injector Connector: Bosch EV6 (as per factory)

Modern Muscle Management: Gen IV LS DBW Ready Harness (EV6)

The GM Gen IV LS engine (LS2, LS3, L98, L76, etc.) represents a pinnacle of pushrod performance, utilizing advanced features like Drive-By-Wire (DBW) throttle control. The Haltech Elite 2500 Terminated Harness for Gen IV LS engines is engineered to fully support these modern architectures. This harness is DBW Ready, meaning it includes the specific connectors and wiring required to run the factory Gen IV electronic throttle body and pedal, bypassing the need for a separate throttle controller module. It is terminated with Bosch EV6 (USCAR) injector connectors, matching the factory fuel injectors found on LS2, LS3, and most Gen IV truck engines. This Plug’n’Play engine harness transforms a complex engine swap into a straightforward installation, perfect for retrofitting modern LS power into classic chassis.

Factory Integration, Aftermarket Control

This harness is meticulously laid out to route cleanly on an LS engine. It connects directly to the factory sensors (Cam, Crank, MAP, Temp, Knock) and ignition coils (via the factory coil sub-harness 7-pin connector). The integration of the fuse box and relays simplifies the chassis side of the wiring—you only need to connect a few power and ground wires to get the engine running. The harness is also pre-wired for a Haltech CAN Wideband Controller (WBC1/2), allowing for precise closed-loop fuel tuning. This version is designed for Manual Transmissions only and does not include wiring for an electronic automatic transmission (like the 6L80E).
