1jzgte harness and ecu into 2jz

[2jz_soarer]

ive been searching for a while,and i cant find the info,

my question is, will a 1jz harness work on a jdm 2jzgte?and if so with what ecu? 1jz or 2jz?

thanks

First problem i see, is the 1j harness is likely from an RHD car so it will have to be modified to fit a LHD car. But its possible, someone here ran a 2j on 7m electronics. The question is, are you capable of making it work?

Yes its already modified,I'm sorry I should of been more specific,
I currently have a 1jzgte in my sc300,but I'm going to swap in a jdm 2jzgte,so I was wondering if
I can still use my 1jz harness/ecu into my 2jz?or if I just need a 2jz ecu
