Now what if I wanted to wire some up to a separate switch? Say a set of off road lights for blasting around in the snow? I do a lot of driving through crazy snow (lake effect snow+living in the middle of nowhere=teh suck), and the brights don't *quite* cut it sometimes. A set of off road lights/rally lights mounted at headlight level should do the trick wonderfully, but I don't want them on when I'm driving around town.Yea, should add a relay. It goes Fogs > Relay > Headlight Fuse(+). Everytime I turn my headlights on, they come on.
That lower left green wire, tap that into where the headlight fuse goes into in the fuse box under the hood.
This is a relay you can get from Pepboys or whatever in the section where all the Pilot brand fog lights are.
I figured it out, I just wasn't sure what that wire would lead to. Say I want to make sure that I can't accidentally leave them on when I leave the car (lights turn off when I turn the car off). I found another diagram:You can put a switch in.... Like what the diagram shows, that green wire with the switch on it.
This reminds me of the lights-on reminder I wired up in my wagon. I have a beeper wired to the parking lights, so that if the key is out of the ignition and the parking lights are switched on, the beeper sounds.When you turn on the park lights the fogs can come on if you switch them on.
I personally think that all aux. lights should be connected through a relay and as all other electronics they should be fused. Why would you not use a relay? They´re cheap, they get more voltage to your lights (That is, if the wiring is up to par) and they let you use smaller switches and protect your OEM wiring.my fog lights are tapped into my parklights with no problem. but gonna switch to a switch soon because switching to yellow hids instead of bulbs. so if your using halogen bulbs your fine tapping into the park lights
