Engine bay wires

I have a 1986 Camaro with the 2.8l multiport with AC(the AC was deleted when I got the car) There's some wiring that I'm unsure of.

I believe the purple is the O2 sensor

These are a red wire then black wire and blue with a black stripe wire.

This is a black wire and a blue wire, up by the alternator, battery, radiator fan area.

By the brake booster (gray, light blue, solid green, and 2 green/white striped wires)

The black and blue is for the ac pressure switch in the line.

the rectangle thing is for some kind of relay... Normally the cooling fan relay.
