Ok guys im stuck on my swap. as im gathering all my parts i remembered i still need to modify the wiring harness to make my TOYOTA SOARER from na 2j to aristo 2j gte.

Now ive been thinking about it and since everybody has to rewire there sc300 bc they are swapping in a JDM motor so the pinouts are different and such. (you know what im talking about i hope) Anyway.... Since i already have a "JDM" wiring harness as it is a true soarer will i even need to modify the harness for the gte or do i get to just plug in and have fun...

NOTE I DID SEARCH THIS. i couldn't find anything relevant to my particular situation.

Thanks for any help fellas.
