OK, so I have a base model Rx-8 and i have fog lights that I need help on. I do not have the kit, which includes a different light switch for fogs. I want to make a switch next to where the DSC button would be, like Unser's switch, only I have a different purpose for it. I need it to toggle the lights on and off. Any one know witch wires i need to run through the switch to make this possible?
Thanks!

Im not good with electrical schematics or anything.. but this might help...

OK I basically got it, sorry for triple posting but its an update/bump thing :-p
OK, i found this:

2 Questions:
1.From my under standing of this.. P connected to D = fogs on right?

2.I got a switch its has 3 connectors on the back, one is for ground, one for power, and the middle for something else (electronic gurus would know). Now this is my question... is P connected to ground or power? And D is connected to the opposite i assume... Or does it not matter what they are connected to as long as one is on power and another is on ground.

The key there is the fog-light RELAY. The fog lights will be drawing close to 10 amps (or even more if you've purchased high-power fogs). It would take quite a large switch on the dash to handle that kind of current. Any small toggle switch you'd install on the dash would probably arc and/or melt in short order and would be hazardous. The stock fog lights are switched on and off by the relay that you circled. A relay is a high-quality switch capable of turning on and off the current draw of the fog lamps. The relay also has connections for a much lower-current wire (the right-hand side of the relay in your diagram). That low-current wire eventually leads to the switch that you operate in the cockpit. It only needs to carry enough current to power the small electromagnet in the relay -- and THAT closes the high-current switch in the relay.

Check your fuse-box to see if you have the FOG relay. If not you should order one and use that in your circuit. You could then switch your aftermarket fogs with the factory switch (if it's wired), or from the separate switch you have installed. Keep in mind though the factory relay is meant to handle the 55-watt oem fogs. That's 110 watts of power (about 10 amps at 12 volts). If your aftermarket fogs are significantly higher wattage you'd need a beefier relay.

the fog lights im using are stock, h11. If you read my other thread in this section you'll see than i used a switch raetd at 30amps to control what i thought is the fog controll inside the cockpit. I seem to have a fog relay(big black cube thingy) in the fuse box. Thanks for your help so far nubo... I think i'll check for any shorts in my setup...

Glad it's working. I'm still not clear on whether you're switching the relay, or using your switch to work the fogs directly. If it's the latter, you might still want to consider employing the fog relay. It's better to keep the high-current switching outside the firewall instead of in the cockpit.

no... its switching the relay. I did the fog light rewire too with Omicron's twist to it. Now it works whenever the key is on ACC or ON :-D
