EMU Black Plug-and-Play Adapter Harness

The ECUMaster WHPIS3001 is a plug-and-play adapter harness engineered to facilitate the installation of the ECUMaster EMU Black standalone engine management system in specific Lexus vehicles. This harness is designed to work seamlessly with the 2001 Lexus IS300 and the 1998-2001 Lexus GS300 models. A key feature of this adapter harness is its parallel design, which allows the original factory ECU to remain in place. This ensures that essential functions, such as the automatic transmission control (if equipped), are still managed by the stock ECU. Consequently, the ETSC-i throttle body must remain connected to the original ECU, meaning the EMU Black will not directly control it. The adapter is compatible with both manual and automatic transmission vehicles, as well as the dash cluster, HVAC system, and throttle body. Included with the WHPIS3001 harness kit are the adapter harness itself, an Intake Air Temperature (IAT) Sensor Kit, and a Bosch 4.9 Wideband O2 sensor. Fitment is confirmed for a range of Lexus vehicles including the 1998-2001 GS300 Base models and the 2001 Lexus IS300 Base model. It is also compatible with JZS161 Aristo, JSX110, and JZS171 models. Always confirm fitment with your specific vehicle details before purchase to minimize the risk of ordering an incorrect product.
