Icon5 need help with how A/C wiring is connected ?

car is a 1990 CRX Si, the A/C quit working in 2005, i had a mechanic try to fix it, and he got it to where it was blowing cold air again, but did'nt get it all done, he cut the A/C harness wires that come out of the firewall and put the rest of the A/C wires in a bag, and i was going to get him to finish another time, he told me its not much left to get so its working again though.
now i want to connect the A/C wires back on the car, and i need to know where each wire leads to ?

the wires that are cut coming out of the firewall are three blu/red wires and two blk/yel wires,

my question, or what i'm trying to find out is where each of those wires from the firewall supposed to lead and connect to ?, also, how do i differentiate between each of the three red/blu wires, and what each goes to ?, and same for the blk/yel ones ?,
i assume one wire comes from the firewall and connects directly to the condensor relay ?, and maybe another one goes to the compressor/clutch relay ?, and the other maybe to the "diode" ?, and the blk/yel wires possibly go to the engine wire harness and also to the ecu somewhere ?, and looks like the loom leads from those relays and then goes to a round white plastic plug connector, which could either be the connector for the condensor fan ?, or the thermostatic switch ? (this is all just my guess, ... but tell me otherwise)
crx a/c wire harness with looms off of it, i wrote in red what i thought those were?

so any help on where each connects to and what routing / order they go in ?, i would appreciate it, thnx

btw, that is'nt a picture of my ac wiring harness, maybe i should'nt of put that picture, cause it confuses and looks like i am asking how to connect that one all together or something, i just put that pic to be able and see how it looks with no looms on it, to see the sections of wire and how they connect to each other to make the whole thing.

i feel like deleting this post and re-writing it, making it much more simple, cause i ended up writing too much stuff on this post, where it kind of makes it look like more of a complex problem or question, when really its not, and is a very simple question, i just need to describe it better without so much extra details, ......
