ECUMaster USA Plug and Play Adapter Harness for EMU Black Lexus IS300 GS300 1998-2001
$854.05

If you’re diving into the world of tuning your Lexus, this plug-and-play adapter harness is a game changer for anyone with a 2001 IS300 or a 98-01 GS300, including the JZS161 Aristo, JSX110, and JZS171 models. What I love about this setup is how straightforward it makes the installation of the EMU Black. You don’t have to mess with the original ECU, which is crucial for keeping your automatic transmission in check if you’re rolling with one of those.

Now, let’s talk about the nitty-gritty. This adapter harness is designed as a parallel harness, meaning it lets you keep the stock ECU in play. That’s important because the ETSC-i throttle body needs to stay connected to the original ECU to manage the automatic transmission properly. So, while the EMU Black is doing its thing, it won’t directly control the ETSC-i TB, but that’s okay—it’s all about keeping things running smoothly.

Whether you’re rocking a manual or automatic setup, this harness has got you covered. It’s not just about the engine; it also connects to your dash cluster and HVAC system, making sure everything works in harmony. You won’t be left with any weird dashboard lights or HVAC issues after the swap.

What’s in the box?

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

This isn’t just a bunch of parts thrown together; it’s a thoughtfully designed solution for those who want to push their Lexus to the next level. So, if you’re ready to unleash some serious potential in your ride, this EMU Black adapter is a solid choice. Just remember, it’s compatible with the Lexus GS300 from 1998 to 2001 and the IS300 from 2001. Happy tuning!
