Trying to Label my harness

Trying to figure out what everything is so I can get it all hooked up properly bought it half swaped and trying to get it done. I believe the first picture is my tps and I don't believe it's factory as there is nothing remotely close to it on the harness to connect too and jm very confused about it

First picture: aftermarket
Second: O2 sensor in your hand
Third: BAC top right, other two OMP
Fourth: ground and IAT
Fifth: Green and yellow are check connectors, white appears to be your boost/pressure sensor

Just put the engine back in my 90' vert, i have a couple videos about how the harness routes, and a picture of most all of the connectors, PM me if you want them. On an n/a vert the black connector in #4 is for some sort of air control solenoid below the intake air temp sensor.

I missed the literal one in his fingers! Yes, it could either be for AWS or ASV, if you follow the wiring diagram the colors are the same and they are activated by the ECU at the same time. There's also one in the background of the third picture where I pointed out the BAC and OMP connectors.
