The Standard for LS Swaps: Gen III LS1/LS6 Terminated Harness
The Haltech Elite Terminated Harness for GM Gen III LS1 and LS6 engines is the gold standard for wiring simplicity and reliability. Designed for the traditional mechanical cable throttle setup found on the Camaro, Firebird, and Corvette C5, this harness completely replaces the aging and often brittle factory loom. It is terminated with Bosch EV1 injector connectors, matching the factory hardware of the Gen III platform. This harness is the ideal choice for engine swaps into vintage muscle cars, drift cars, or any application where the reliability of a brand-new, motorsport-grade wiring harness is required over a reworked 20-year-old factory loom.
Plug, Play, Perform
This harness supports all the standard Gen III sensors, including the 24x crank sensor, rear-mounted cam sensor, MAP, IAT, and Knock sensors. It features a fully integrated fuse block and relay box, handling the main power, fuel pump, and ignition power circuits. By utilizing the factory coil sub-harness connectors, it allows for easy coil mounting and replacement. The harness is constructed with high-temperature automotive-grade wire and sheathing, ensuring it can withstand the rigors of the engine bay environment better than OEM wiring.
