Cable Throttle Conversion: Gen IV LS Non-DBW Harness (EV6)
For racers who prefer the mechanical simplicity and instant feedback of a cable-driven throttle body on their Gen IV LS engine, the Haltech Elite Terminated Harness (Non-DBW) is the engineered solution. This harness is designed for GM Gen IV LSx engines (LS2, LS3, etc.) that have been converted to a mechanical cable throttle. It removes the Drive-By-Wire wiring complexity, streamlining the harness for pure performance applications. This specific version is terminated with Bosch EV6 (USCAR) injector connectors, making it a direct fit for factory Gen IV injectors or high-performance drop-in replacements that utilize the EV6 standard.
Optimized for Engine Swaps
Converting a Gen IV engine to cable throttle is a popular modification for track cars and retrofits into older chassis where installing an electronic pedal is undesirable. This harness supports the Gen IV’s 58x crank and 4x cam signals but is wired for a standard TPS and IAC (Idle Air Control) motor found on mechanical throttle bodies. It features a fully integrated fuse block and relay center, ensuring reliable power distribution. The harness plugs directly into the factory coil sub-harnesses and includes wiring for a Haltech CAN Wideband Controller. It is the cleanest way to wire a cable-throttle LS3 or LS2 into your race car.
