Finally! We have the pre-fabbed off the shelf harness to run all of the ECU and engine related components for a 2.0 WRX or 2.0 STi engine platform you are looking for.

Let us handle the leg work for your custom project.
This harness takes the basic setup of the 2.0 Project Harness and finishes it out to make it as easy as possible to install. We've wired up the weatherproof fuse box that houses all of the necessary components to run the ECU, radiator fans, and fuel pump. In addition we've taken care of the alternator, cluster leads, and most other engine related components. All you need to do is hook up a few simple inputs and outputs.

  • Key On Power Input
  • Starter Trigger Input (ECU just wants to see when the starter is cranking)
  • Battery Input (Circuit Breaker Included for Circuit Protection)
  • Fuel Pump Output
  • Radiator Fan(s) Output
  • Cluster Related information
    • Tach
    • VSS
    • CEL
    • Oil Pressure Light
    • Alternator Warning Light
    • Fuel Level
  • Plug in Fuel Pump Controller (Fuel Controller Not Included)
  • Plug in Alternator
  • Plug in to Main Engine Connectors on the Sides of the Engine

Utilize the Built in OBD2 Port for Diagnostics and Tuning
The OBD2 port, flash connectors, and initialization connectors are all prewired so all you have to do is plug in to the OBD2 port with your scan tool of choice to read any diagnostic trouble codes. Reflashing and tuning will function just as it would in the car the engine came out of so take it to your local tuner and let them get the most out of your new turbo platform.

2 Different Standardized Layouts designed for your application.

  • Rear Engine - This version is designed for vehicles like VW, Porsche, Sandrail, or Kit Car where the engine is mounted in the rear of the car.
  • Front Engine - We set this model up for your Subaru race car with the engine in the front

Fitment Notes

This is not a complete replacement harness for a 2.0 WRX application since it runs the bare necessities of the engine only. It also is not a good option for a non-turbo to turbo swap since that project should be accomplished with a harness merge.
