It's the + or the - that is switched on our fog lights. I'm trying to think of a simple way to have my fogs stay on with my high beams. I was contemplating using the relay that I installed with my driving lights that is fired by the high beams to light the fogs also. It's a 30 amper so load wouldn't be an issue. TIA

 

Not sure on the 2003 but on a 2004 the White wire with a Yellow stripe is the switched lead for the fog lamps and it's +. The black wire is - and it goes directly to ground.

If you have a volt/ohm meter you could verify this before connecting your wires.

Connect your + from your driving lights to whichever wire that isn't black going to your fog lights. Again, on a 2004 it's the white wire with a yellow stripe.

 

Cool, yeah I'll just test it out when I get home, it's easy enough. However right now I'm a 2 hr flight, and an hour drive from home, stuck in camp for the next couple of weeks. Just hoping to get a head start on the plan! Too easy if it is + switched, seems to me my 01 gasser was -. Thanks mister.

 

You are right, sort of. The fog light relay is tripped with a ground sense from the fog light switch. But once the relay is tripped, it sends 12v+ down the wire (white wire with yellow stripe on a 2004) to the lights.

In your case, it sounds like you won't be adding any more relays or tripping any relays. All you are doing is taking the 12v+ output from your driving light relay and sending it to the fog lights.

I want to do this also, It sounds like all a guy has to do is run a jumper from the output of your highbeam to the positive lead of our fog lights. My only question is, do we need an electrical checkvalve( electrical ignorance, my bad) between the high beam and fog light. If you just wanted to run fogs and lowbeams, wouldn't the the jumper back feed power to the high beam? To me, it sounds like you would only be able to run just lowbeams alone, or highs and fogs only. In foggy conditions, highbeams would be terrible with fogs on.

 

That "checkvalve" is called a diode. Radio Shack has a bunch. Yes, if you want to run the fogs without the high beams, you'll need to put a diode in your new wire from the high beams to your fog lights. Make sure you put the diode in going the correct direction.

 

Thanks Handy

Another dumb question, do they have an arrow on them? either that or trial & error always works, I usually recieve an error first

 

Nope, they don't have an arrow. They have stripes and the stripes should be toward the device using the power. i.e. the lights.

 

Funny you should mention that DSLRammin, I came to the same conclusion on the drive home tonight. I think I'll probably just end up using another relay, it would certainly suck to have the drivers on anytime the fogs were on.
