Recently been redoing my interior in the mr2. I'm planning on starting the 2GR swap in the next couple of months. I got some questions regarding the wiring harness again...
1.) What sections of the wiring harness do I need from the 2GR? Engine, body, and or both?
2.) If I get an engine that is not from the same car as the harness will it still match up. Say an Avalon engine and rav4 or sienna wiring harness.
