Haltech NEXUS Rebel LS Terminated Harness for ECU

Description

Haltech NEXUS Rebel LS Terminated Harness
​The Haltech NEXUS Rebel LS Terminated Harness (HT-186500) is a professional-grade, “drop-in” wiring solution specifically engineered for GM LS Gen III and Gen IV engine swaps. Designed to work exclusively with the NEXUS Rebel LS ECU, this harness eliminates the complexity of custom wiring by providing a pre-terminated, labeled, and plug-and-play interface for the entire engine.
​Key Features & Benefits
​Plug-and-Play Integration: All major engine connectors are pre-installed, allowing for a seamless connection to factory LS sensors, including crank, cam, coolant temp, and oil pressure.
​Modular “Breakout” Design: The harness features a unique breakout system for high-customization areas. This allows you to easily swap sub-harnesses for different:
​Injectors: Support for EV1, EV6, or Multec 2 connectors.
​Alternators: Adapters included for 2-pin Bosch, 4-pin Delco, and 2-pin Yazaki styles.
​Throttles: Compatible with both Cable (with IAC) and Drive-By-Wire (DBW) setups.
​Built-in PDM Functionality: Leverages the Rebel LS ECU’s internal power distribution to directly power high-current devices like fuel pumps (25A) and cooling fans without the need for external relays or a fuse box.
​Advanced Connectivity: Includes a dedicated CAN Bus connector (DTM-4) for instant integration with Haltech iC-7 dashes, keypads, and expansion modules.
​Premium Construction: Constructed using automotive-grade, heat-resistant wiring and high-quality sealed connectors to ensure reliability in high-performance or racing environments.
