    just download the wiring diagram and read thru it
    or u can send me your looms and I can wire it up
    its not a 5 minute job

    the other big prick of a job is your ecu is in engine bay and Cressida is behind dash
    so making it neat is a pain or you can extend the engine loom and fit ecu under dash

    u need to power ecu
    power coils
    power injectors
    and fuel pump
    just run them all to a big switch like most on here do
    and then the starter and alternator and it should start

    u need to make drawings of your plugs near the ecu
    both for cressdia and 1jz
    otherwise u will never understand
    what madmont has described above is fine if u know what Toyota symbols mean and plug layout
    if you do these day in day out but looking at diagrams is useless unless u know where the wire is

    I did a jzs171 in a supra afew months ago
    took me awhile cause I lengthend the loom so ecu sits under dash

    I need to charge that much because I have to ask the wife to take a day off from our xmas holdays to drive to dubbo wire your car and drive back all in a day then 2 days after then drive back home to qld

    Could be a problem finding room for the ECU box under the bonnet of the MX83
    May have to relocate the battery as I did for my Hilux if ECU was left under bonnet
    See picture to left. ECU is in bottom right of picture where battery used to be
    Battery now where the air cleaner used to be with a Suzuki air cleaner behind it

    yes I was lucky I had plugs and about a foot of wire on them from a vvti 1uz so u lengthened all wires
    took half a day just to lengthen all wire properly but it looked much better
