how different are the wiring harnesses from the 2.3 to the 2.0? i figured the swap would be straight forward, but you talk about the wiring like its hell... how much of the 2.0s harness could i use? also would i have to change ECU's or could i just flash the engine to run a 2.3? also tuning is allowed, do you need a flasher of some sort? like my WRX you can just flash the stock ECU without a tuner/flasher... can you do the same with the foucs ECU? i have a bunch of questions if you can tell... ive got a lot more if you dont mind
