Default Anybody have a 99 SC300 ECU plug diagram?

Does anybody have an ECU plug diagram and or pinout for a 99 SC300? I was gonna try too get started on my wiring harness tonight for the Aristo GTE swap, but was stopped cuz I realized all the info I have on the GE harness and ECU must be for later SC300's.

My ECU and wiring harness for 99 Auto SC300 is actually 6 small plugs instead of 2 big ones.

Can anybody shine some light on this?

Thanks

nope. that wont help you; unless you are willing to backprobe and trace every single wire and find the differences-

TT/na is not going to be the same, its not really going to help u figure out your initial problem- you don't know what you are working with. map of another brain won't be that spot on.

have you tried going to the toyota dealer and asking them to print you out a pinout? it would be the easiest way, thats what I would do if I had your puzzle

you could also try the is300 forums, their car is pretty close; model year 2000 vvti 2jz-ge right?

Does anyone know what series the terminals and connectors are for the 98+ ECU connectors?

Are they Sumitomo and if so what series?
