Nexus Rebel LS – Bosch Pedal adaptor

Drive-By-Wire Pedal Interface for Bosch Pedals

The Nexus Rebel LS – Bosch Pedal Adaptor connects the Accelerator Pedal Position (APP) breakout on the Rebel LS main harness to a standard Bosch Motorsport DBW Pedal. The Rebel LS harness is designed with a generic breakout for the pedal; this adapter makes it plug-and-play for the widely used Bosch pedal unit, popular in motorsport due to its reliability and availability.

Engineering Deep-Dive: Redundant Safety

DBW pedals utilize two potentiometers (APP1 and APP2) that move in correlation to verify pedal position for safety. This adapter correctly routes the 5V reference, Sensor Ground, APP1 Signal, and APP2 Signal wires from the Haltech harness to the specific pinout of the Bosch pedal connector. This ensures the ECU receives valid, redundant signals required for safe throttle control.

Operational Benefits: Motorsport Standard

Using a Bosch pedal is common in custom pedal boxes (Tilton, Wilwood) or as a floor-mounted solution. This adapter saves the user from having to crimp the specific Bosch connector, ensuring a secure and reliable connection for the most critical driver input.
