im not sure
if u have any pics that would help
when i do my wiring i dont really go of the year as soo many crap and wrong diagrams out there
i go by the pins and colours and make my own diagrams
all i know is its an ealry ls400 / celsior ecu
i want 250 aussie dollars for it
you can prob get one cheaper if u search or ring round
i have alot fo spares but dont go out of my way to sell them
just if something comes up as i dont make much money on selling parts
