2ZRFE and manual swap 2007 hatchback - Toyota Yaris Forums

Your list looks mostly complete:
-Yaris body harness: keep
-AC: You'll also need hoses and I recommended swapping the condenser for a new one. Flushing it will be a pain.

On engine and harness:
I recommend going with the Scion XD ECM and engine harness if possible. This will reduce manual wiring to just a couple wires and ensure compatibility with the body harness. Additionally, a US Scion XD ECM will not have an immobilizer, which should mean it will work with any engine/body. If you want to maintain the immobilizer, then I'd suggest going with a Corolla ECM and getting your keys reprogrammed.

A Corolla engine harness with a Scion XD ECM should work, but you'll want to check the pinout on both to make sure these match up.

Keep in mind, the ECM and harness is also transmission specific, i.e. manual ECM and harness can only be used with a manual transmission.
