OEM Fog Light Switch, wiring... Options

[UTSlickVic]

Well I'm installing my OEM Fog Light "push" Switch I got on ebay- Switch located beside diver side vent. Its of of a ST202. I figured its alot cleaner look than after market switches. Anyways, I ran into some confusion on how to wire it. There are four wires. But the wiring (not stock) leading to my fogs now only consist of 2 wires- well at least from a quick glance under the dash. However, the wiring was from after market fogs (later I just hooked up OEM fogs using the same wirring) came with a light up switch (which I did not use). So I think the wiring has capability of lighting up a switch (I think).

Need some direction...

Does anyone know what each wire does? Can I neglect a couple of wires?

here's a pic of the OEM wiring from the button.

bump... for HELP

I must be color blind... OK, this is what wires I have coming out of the OEM switch:
GreenRed/Orange
White/Green
Red/Green

The wire colors I have on my aftermarket fog wire harness are:
Red
White
Black

I know what these (aftermarket harness) wires do, but what the hell do the OEM colors signify? Help... ?
My first attempt thus far has been connecting the following

OEM ------ Afternmarket Harness
green ---> Black
red/orange -----> did not connect (assumed it was illumination)
white/green -----> White
red/green ------> Red
This was just a test to see if it would work...this did not work.

I kinda followed what Hanyo listed. Can anyone give me some recommendations? I may have to just go junkyard hunting to look for an OEM harness.
