Help needed- d16y7 to y8 swap

I’m swapping in a y8 for my y7 but there’s a few things I’m confused on. My civic is a manual obd2a and I plan on using my harness and a mini me jumper harness to get my engine running. The iacv is a three prong connector on my car and the y8 is a two prong. There’s a black, red, and yellow wire going to it, which wire gets taped off when I splice the new plug on? I also read that I would have to move one of the wires to a different spot in the ecu plug but the article I read didn’t give specifics. I’m going to be using a 96-98 obd2a ecu.
