eta harness to I harness

[Batz]

Im doing the a 2.7i swap into my, whats used to be, eta car. I was wondering if this is all i need to do with the wiring or if theres more, or other diagrams and etc. (Im planning to cut the square one out and make it just two circle connectors)
Thanks

Electrical troubleshooting manuals are your friend.

Okay, i dont want to sound stupid, but i checked and i dont get anything..
I opened the 1884 325e one and 1888 325i. all i see is the diagnostic connectors... not really what im looking for... Can someone please explain it to me like to a 5 year old?

For some reason, the whole C101 is never listed in one place. Go through every page and look for "C101". Note the pin number and the color of the wire on both sides.
