I have ecu listed. What changes wire harness wise?
The 2ZZ has wires the 1ZZ outright doesn't have and vice versa. The same applies to early vs late model years of both engines, so you need to also make sure you're keeping track of that as well. Theoretically it should work fine.

For lift I believe if you are going from 1zz to 2zz but the reverse means I already have those and don't need them for the 1zz I belive.
The ECU is different, as are the transmissions. The intake system isn't exactly the same, knock sensors vary, as well as other sensors. You need to triple check everything involved and ensure it will wire up properly. There are countless threads of electrical nightmares post ZZ swap, even basic swaps with the same engine can be troublesome.
