Mini-me engine harness question

Hi guys, I am doing the conversion of my 98 Civic Non-VTEC with a D16Y7 engine to a Y8 head Yesterday I found a relatively clean 2000 Civic EX 4-door I extracted the engine harness from and almost everything fit well with the Y8 intake manifold but I noticed 4 things wrong with it.

1: I couldn't find the connector for the EVAP canister sensor, I already checked the harness like 3 times and no idea why the connector isn't there, I couldn't find like a cutted cable that suggested me the connector was trimmed off the harness, so, maybe this version of Honda didn't have a sensor in the canister?

2: There is a O2 sensor connector behind the engine, but I noticed it looks really similar to the male connectors my Y7 sensors, so I am unable to connect them since they both are males, should I modify my O2 sensor to adapt to this harness?

3: So, there is a connector for the O2 sensor behind the engine (under the intake manifold) but I couldn't find the connector that goes in the exhaust manifold, I think is it called the primary O2 sensor, so is this connector chopped of or maybe is part of the headlight harness or something?

4: The distributor didn't match with this engine harness, instead of having the big squared blue connector it has a rectangular white 8 pin connector, maybe this could give you the idea what harness I have and how could I address this, should I get the correct distributor or can it be adapted?
