Default ECU Help Please.

Can someone with a little more experience in 2jz's tell me what exactly is going on here??



I am not quite sure why these three plugs are different ? either the engine is not what i was told it was ('01 GS300 2jz-ge vvti *auto) or the ECU is not what i was told it was (2jz-ge vvti *auto). And can some one please enlighten me and shine some light on the Immobilizer? Can I bypass it?

thanks
Ryan

I am unsure on the plugs. You cannot bypass the immobilizer, I just put a used ecu in my is300 and I had to match the key to the ecu. This is done by a qualified shop or locksmith and it aint cheap.
