rb20 wiring issues

[Boostnasty]

im currently wiring a rb20 into a s13. Ive been searching through all the usual writeups and have several question about the few wires remaining. Heres the problem

first off the Brown plug to the KA harness near passanger side fuse box. red/black(ECU relay) and black/yellow(IACV), i have no idea where this connects to rb harness. i have ecu backup/ constant power already connected on gray KA connector, which im guessing is memory.

next, the KA gray oval plug on KA harness near passanger side fuse box. There is a black/white wire(ECU power) and yet again i have no idea where this connects to rb harness. Also i have 2 unidentified wires on this plug, an extra blue/green and orange/ blue. One is suppose to be ground for the plug so i should be able to figure that one out just through testing them as a ground but any info on that would be appreciated as well.

ive used these writeups so far
