Below are several wiring diagrams that are useful for wiring a 2gr-fe into a swapped application, I am working on adding more diagrams to this page to cover more applications.

Note that this diagram does not show all the wires in the main harness that do not need to be modified

Wiring diagram for 2GR-FE integration into 1993+ MR2 Turbo (based on 2009 and earlier RAV4 harness and ECU)

This diagram shows the engine harness needed to swap a 2GR-FE into a 1993+ turbo, note that this includes all of the chassis integration parts that aren’t part of the engine control but sit on the engine harness, Things like the reverse lights and such. Note that Toyota changes colors quite often so do not count on wire colors to be correct.

This is the entire stock rav4 wiring diagram with emissions removed to reduce diagram size. This can be useful when debugging. Note that the lightbox tool cannot handle an image this wide, click here to download the full version.

AEM standalone ECU wiring diagram

Note i do not actually recommend using that aftermarket ECU but the diagram is likely useful for many others looking to use another aftermarket ECU with the 2GR-FE.
