Haltech Nexus Rebel LS - Cable Throttle + IAC sub-harness

Haltech NEXUS Rebel LS Cable Throttle and IAC Sub-Harness

Part Number: HT-186504

The Haltech HT-186504 sub-harness connects the throttle breakout on the NEXUS Rebel LS main terminated harness to a cable-operated GM LS throttle body.

It provides direct connections for the throttle-position sensor and idle-air-control valve, allowing a Rebel LS installation to use a conventional cable throttle without modifying the main engine harness. This is the throttle sub-harness supplied with the Gen III Rebel LS kit.

Key Features

• Connects a cable-operated GM LS throttle body
• Provides connections for:
  • Throttle-position sensor
  • Idle-air-control valve
• Plugs directly into the throttle breakout connector on the HT-186500 Rebel LS main terminated harness
• Fully terminated for straightforward installation
• Allows conversion between cable-throttle and drive-by-wire configurations without cutting the main harness
• Direct replacement for a damaged or missing Rebel LS cable-throttle sub-harness
• Supplied as standard with the HT-220201 NEXUS Rebel LS Gen III kit

Application Notes

• Designed specifically for the NEXUS Rebel LS terminated-harness system.
• Requires the HT-186500 Rebel LS main terminated harness.
• Intended for compatible GM LS cable-operated throttle bodies equipped with a throttle-position sensor and idle-air-control valve.
• This sub-harness does not support an electronic drive-by-wire throttle.
• Drive-by-wire applications require the appropriate Rebel LS throttle and accelerator-pedal adapter harnesses.
• Confirm the throttle-position-sensor and idle-air-control connectors on the throttle body before ordering, particularly when using an aftermarket throttle body.
• Throttle body, throttle cable, accelerator-pedal assembly, ECU, and main engine harness are not included.
