RB20 into 92 S13 HELP! WIRING, CONNECTORS

[Orangevirus1]

Ok I have looked over just about Every damn "wiring guide" on the internet, and frankly the guides freaking suck..

Oh find the grey oval plug.. there is like 10 freaking grey oval plugs.

anyway. my car is a 92 240sx KA24DE AUTOMATIC transmission

that I am converting to a RB20DET "gold" top ( I guess that is considered Silver? lol ) I dunno.

OK so Throughout all the guides, I haven't really found much about the connectors Shown in the pics below, and what I have to do with them.
ALSO, Notice on the ORANGE Harness ( RB harness ) the pic with the Free wires circled in BLUE!, well they were cut by the person who sold it. I'm guessing it goes to the MAF and 02 sensor? Anyone have the Color codes for the MAF and 02 sensor plugs ?

NOTE : on the pics, with the connectors circled with RED, what do I do with all these things.
ALSO the pic with the BROWN connector ( KA harness ) what Do I do with the OTHER side of that plug ? ( up in the dash )
the online guides say nothing about all this...

You may need to download a couple of FSMs and start looking through the wiring stuff.

From my experience, the 1991-94 S13 FSM has better wiring diagrams to you may need to download those too.
