Brand new Toyota OEM engine wiring harness (from 2007 Rav4). Fits all 2GR-FE engines, plugs in to the OEM ECU that MWR sells. Usually if your used engine comes with a harness it’s cut up or it’s the wrong style harness. Simplify your install and improve reliability with this harness.
This is the engine wiring harness only and is the larger of the two connectors at the ECU. If you’re swapping a 2GR into a car that didn’t come with a 2GR then you will need the small connector (sold separately) and wiring which you’ll need to integrate with your car’s body harness.
