Elite 2000/2500 GM GEN IV LSx (LS2/LS3 etc) non DBW Terminated Harness Injector Connector: Bosch EV1

High-Flow Mechanical: Gen IV LS Non-DBW Harness (EV1)

The Haltech Elite Terminated Harness (HT-141364) is specifically configured for high-horsepower GM Gen IV LSx builds that utilize a mechanical cable throttle body and aftermarket fuel injectors with Bosch EV1 connectors. This harness bridges the gap between the modern Gen IV engine architecture (58x crank/4x cam sensors) and the traditional high-flow fuel and air components preferred in drag racing and heavy-duty street applications. By using EV1 connectors, this harness accommodates the vast majority of large-cc aftermarket injectors without the need for additional adapters, reducing resistance and potential failure points in the injector circuit.

Race-Ready Construction

Designed for the Elite 2000 and 2500 ECUs, this harness eliminates the complexity of adapting a factory Drive-By-Wire loom to a mechanical setup. It includes connectors for a standard Throttle Position Sensor (TPS) and Idle Air Control (IAC) valve. The integrated fuse box and relay assembly provides a consolidated power center, simplifying the chassis wiring significantly. Whether you are swapping an LS3 into a Fox Body Mustang or building a dedicated drift car, this harness provides the robust, terminated solution required for reliable engine management.
