from what i have read i would have to say yes
You may want to change your ECU also, the ports are different, so your fuel requirments will be different, although a PC and a custom map may solve that for you.
It's basically the exact same engine, yes it will bolt right in.

Yes, you should be able to use the 03 wiring harness. They should be the same.
