Nexus Rebel LS – T56 Transmission Harness

Seamless T56 Integration for Rebel LS

The Nexus Rebel LS – T56 Transmission Harness is a specialized adapter designed to connect the Haltech Rebel LS Terminated Harness to a Tremec T56 manual transmission. This adapter bridges the transmission breakout connector on the main harness to the Vehicle Speed Sensor (VSS) and Reverse Lockout solenoid on the T56, ensuring full functionality of speed-dependent features and transmission safeguards.

Engineering Deep-Dive: VSS and Lockout Control

Modern ECUs like the Rebel LS rely on vehicle speed for functions like launch control, traction control, and cruise control. This harness provides a shielded connection for the T56’s magnetic VSS, delivering a clean speed signal to the ECU. It also wires the reverse lockout solenoid, allowing the ECU to control the lockout based on vehicle speed, preventing accidental shifts into reverse while driving forward.

Operational Benefits: Plug-and-Play Simplicity

This harness eliminates the need to manually pin out the transmission sensors. It plugs directly into the pre-labeled breakout on the Rebel LS main harness, ensuring a watertight and secure connection.
