Description

The ECUMaster WHPIS3001 is a plug-and-play adapter harness designed for the installation of an EMU Black ECU. It is compatible with select Lexus models, specifically the 2001 IS300 and the 1998-2001 GS300. This harness allows for the integration of the EMU Black while retaining the original ECU to manage automatic transmission functions, if applicable.
