pinout for the foglight switch

This probably won't help a lot but it's all I have on hand right now. I know the pins are right but the colours may be different depending on the year

Interesting. According to that, the fog light switch has 6 wires. According to my car, it's only got 5.

From what I remember, the plug has the wires arranged in a backwards C shape (looking at the back of the switch). The bottom left is ground, the next one up is the high-beam switch (make the switch see ground only to keep the high beams from screwing with you). Then there's a dashboard illumination wire, then there's the top two wires. One goes out to the relay, one comes in providing the power. The power wire on my '01 RS was a Blue/White wire. The output to the relay was Black/White. The dashboard illumination wire was White/Yellow. The two ground wires were Yellow/Blue.

But I believe that's not all you're going to have to do. IIRC you'll need to tap a power wire to the fog light relay as well. Look for the two round relays on the side of the fuse panel. The top one on my car was pink, and controlled the fog lights. There is a Blue/White wire going into it that is only energized when the headlights are on. That needs to get fixed.

Find your ignition-controlled power supply, and connect it to the Bl/Wh wires going into the relay and the switch. Cap off the wire stubs to prevent electrical shorts. On the switch, cut the Y/Bl wire that switches from gnd to +12v, and ground the switch. Cap the wire off as well.
Make sure your power source isn't connected to the dashboard illumination in any way, or you'll end up with fog lights that turn off when you dim the interior lights.

I have a scan for the rear fog lamp not the front my guess is they work the same

the other one
