Hello all, back again. Just received my 1jzgte vvti with auto tranny that im going to be swapping into my 01' IS300, now, I dont have the full wiring harness they were cut off. Does that mean I need to spend another grand just for the harness? Ive been looking around and people have said that the GReddy e-manage will just replace the job of the harness pretty much? Obviously with running the stock IS harness and ECU along with it? Im not to sure hopefully i can get to the bottom of this.. Thanks again!

soooooooo does a standalone or piggyback tuning ecu make the stock 1jzgte harness obsolete or no?

A standalone just replaced the factory ECU to a fully controllable ecu. A harness needs to be properly mated to the motor and the car for it to function properly
