    Default 1JZ-GTE from JZS171 Crown wiring diagram?

    I could finally figure out what has happened to ask the right question. Sorry for that topic with 5-spd a/t.

    So I ordered a full set of 1JZ-GTE from Japan, including wiring harness, ECU, engine and gearbox. It turned out (too late 'cause no one paid too much attention to electrics when physically installing the engine) that gearbox's connectors don't fit the rest of the harness.

    It eventually become evident that the engine is from a 1999-2003 JZS171 Crown while the gearbox is from 1998-2001 JZX100 Chaser.

    So I'm now in 2 troubles:
    1). None of the 1JZ-GTE wiring diagrams found in the web, or at least pin diagrams fit. They all show 4 connectors while the ECU 89661-3A660 have 5. So I can not even guess how to power it up.

    2). I don't know what to do to the gearbox either. If I had its connectors pinout I would decide if I can convert one type of connectors to the other ones. Otherwise my best guess is to buy one more a/t which is extremely rare as I know so far.

    Has anyone dealt with this exact modification of 1JZ? Or even guess where to find/d'load/buy/steal/etc the diagrams I need? Any minds are appreciated.

    Engine conversion is when you drive a shitbox which costs a whole LEXUS to own
