Elite 2500 GM GEN IV LSx (LS2/LS3 etc) DBW Ready Terminated Harness Injector Connector: Bosch EV1

Custom Fueling Solution: Gen IV LS DBW Harness with EV1 Connectors

This Haltech Elite 2500 Terminated Harness is a specialized variant for the GM Gen IV LS platform (LS2, LS3, etc.). While it retains the modern Drive-By-Wire (DBW) architecture native to these engines, it is terminated with Bosch EV1 (Jetronic) injector connectors instead of the factory EV6 style. This configuration is specifically designed for high-performance builds that utilize aftermarket high-flow fuel injectors (many of which use the EV1 connector standard) while keeping the sophisticated electronic throttle control of the Gen IV engine. It eliminates the need for messy injector adapters or cutting and soldering reliable injector clips, ensuring a direct, low-resistance connection to your fuel system.

Seamless Integration

Like its siblings in the Elite Terminated range, this harness completely replaces the factory engine loom. It connects directly to the 58x crank sensor, 4x cam sensor, and other Gen IV specific sensors. The harness includes an integrated fuse block and relay center, taking care of all power distribution duties. It is wired to accept the factory 7-pin coil sub-harnesses, allowing you to use factory LS coils or upgrade to high-output aftermarket coils that utilize the factory sub-harness topology. This harness is the perfect choice for a restomod build where a Gen IV engine is being used with an upgraded fuel system and a manual transmission.
