SR wire harness questions

[nissan_s15_240sx]

I'm needing some information about a few plugs in my SR wire harness. I need to know which plug goes to my power steering line, I have 2 of them and don't know if it's the one with the orange/black and brown wires, or the one with the purple/white and black. I also need to know what it is that the other connector goes to. And I need to know if what it plugs into is necessary or not.

There's also another small plug, it has blue/white and black wires, and I need to know what it plugs into and if it's necessary.

Any help on this would be greatly appreciated!

The purple white is PS. The orange black is the boost control solenoid. The blue white could be an ambiant temp sensor or ABS sensor depending on where it is.

Also on my SR harness where it's supposed to plug in behind the stock 240sx battery location, on my KA harness, there's only 1 green wire w/ a yellow stripe, and on the SR harness there are 2 of them, I need to know if I connect the two green/yellow wires to the one on the KA harness, or do I just connect one, and if so..WHICH? Thanks!

Those wires involve AC, if you arent using AC dont worry about them.

Well I plan to use the A/C....so do you know what I should do with them?

The green yellow is one of the switch wires for the ac relay. You would probably be safe hooking both of the two to the single one. The signal comes from the ECU so if the AC still doesnt work after they are hooked up just hotwire the AC compressor and bypass the ECU.
