I got an 05 Sport, and I'm considering a swap, but my plans require a tunable ECU, and the 05 EJ251 ECU isn't tunable. So, I'm looking at the 2005 FXT ECU, and hoping it hooks up to the 2005 Turbo wiring harness... Failing that, a 2005 Turbo ECU would be better than the 251's ECU anyway.
So, if I was to get a 2005 Turbo wiring harness, how difficult is it to swap? I'm assuming little things will need to be spliced, but it shouldn't be as time consuming as merging a 1997 LGT and 2006 STi harness, for example. But I'm guessing, I haven't had any chance to look at wiring diagrams yet, so I'm asking, how hard is the wiring merge?
