Questions on doing a swap on a 96 civic dx with a 99 Ex motor

So what do I need to swap a on my 96 civic dx.. I found a 99 civic ex I d16y8 motor, wiring harness, and ECU. What else should I need to do the swap to make it as close to plug and play as possible? Or should I look for a different motor?

The '99 engine harness and ECU will NOT work in your chassis... if you want to use the '99 D16Y8, you will need to modify your existing engine harness to work on the new engine and you will need to locate a '96-98 P2P ECU. Make sure it matches the transmission type that you currently have in the '96 chassis.
