I'm not sure which forum this should go in. I found the schematics for the JDM 2JZ-GTE (Aristo) and thought 1 or 10 of you might be interested. I have read it is a direct swap (wiring) into the Lexus GS 300. I have yet to verify the body plug connector (IK1 and IK2), as I'm still going through and filling in the pin-out. It's free and legal near as I can tell. Happy hunting.
