I recently found a 99 Impreza RS in the scrap yard and grabbed a bunch of parts off it, hoping to fit them onto my 95 Impreza wagon.

 

I acquired both fog lights and the switch in the dash, however, couldn't get the entire harness out. I'm obviously going to have to do some of my own wiring to get the lights to work, which is no problem, as I work on and wire emergency vehicles for a living.

 

On the back of the switch are (5) wires. Black w/white trace, Red w/black trace, Black w/red trace and (2) Yellow w/green trace. I've gone through all my Subaru repair manuals, but can't find the schematic for this switch. Can anyone help me figure this out? Power in, grounds, switch illumination, power out to relay, etc. Thanks in advance! 

i cannot remember exactly what they did but i do know that 2 of them perform the switch function one of them is a ground one of them is the switched power for the lamp that shows the icon and the other one is switched power for the red light that says its on. you can probe the back of a connector on one of the other switches to find out what colors do the light bulbs by probing the line and switching the lights on and off see if you get voltage one of them will get power when the lgihts are on. that wire needs to be tapped into and extended to where the fog switch goes to turn the background light on. then probe around the connector again switching the switch on and off for each wire untill you find the color that makes the red light come on for this function i tapped into the power out from the switch to the fog lights to turn this light on. i cannot remember if i grounded into the other switch as well for those bulbs or if i just grounded under the dash. the remaining 2 wires will be for the fog lights them selves. the switch was run into a relay before the fogs.
