Planning on doing a 2JZGTE VVTI Aristo swap into my 01 GS430. Heard of tweak'd performance having a harness made to run both aristo and gs430 ECU. Any info on this and what else do i need in order to make this swap work. Im want to do things the right way even if i have to spend a little more. Will this harness be the best route in order for the swap to work right without any problems?

if you go tweakd it should work. you just have to tell them all the specifics.
