ECU Master PNP For EMU Black for Lexus IS300 '02-'05

This plug and play adapter harness allows for the installation of an EMU Black in an 02-05 IS300 or an 02-05 GS300.  This is a parallel harness, meaning that the original ECU is retained to control the automatic transmission (if applicable). The ETSC-i throttle body must remain connected to the stock ECU to correctly control the automatic transmission. For this reason, the EMU will not have control of the ETSC-i TB. Adapter works for both manual and automatic vehicles), dash cluster, HVAC and throttle body.

What's included?

• Adapter harness
• Intake Air Temp Sensor Kit
• Bosch 4.9 Wideband O2 sensor
