well if you don't swap the front chassis harness, you will atleast need the N/A engine harness installed on the 22t engine, and you will have to move several pins on the ecu plugs and wire in all the boost sensors.

That is ofcourse if you wish to keep the chassis harness on the n/a

Or just swap out the whole front harness with a turbo harness... there's not much to taking the dashboard out at all.

it's much much less of a hassle to just swap the harnesses

uh, i think it's best to pull from the inside, you'll have to remove your hvac stuff as well.

Keep your n/a engine harness and just relocate the coolant temp sensors to the driver's side of the harness and use it on the turbo motor. Other than that, all you need to add are the turbo specific sensor wiring, wastegate solenoid (boost control), MAP sensor, & pressure exchange solenoid.

You will also need to swap the positive leads for the crank & cam sensors.
