Just stay clean and organized. Bag and Label every screw you take out so you know where it goes. Tag all your cable and sensors so you know where they go. Triple check everything before you pull it so you dont break anything.
Just stay cool and when you get frustrated stop. Pulling engines on these new cars is a pain in the ass with all the electronics and shit. I'm currently in the process of replacing the engine in my Chevy S10 and I'm about a day away from the swap. It took me about a day total work to get everything disconnected, so its not really that time consuming.
PM me if you have any other questions, and good luck.
