fog light wires from headlights???

MustangTzahui · 03-26-2001, 01:26 AM

okay,
Is it ok to wire my fog lights (off of a GT to a V6) from the headlights's wires?? I just don't know if it's ok, I know it can be done, but will that affect my regular headlights if I just by-pass those wires onto my fog lights? that way I can use the same switch for both.
thanks

Running the fog lights through the same switch as your headlights may be too much of a load for the switch and cause it to get hot. I suggest installing a separate switch or connecting a single 12V relay to the wires going to one of your low beams and connecting the fog lights through the relay straight to the battery. Don't forget to install an inline fuse!

thanks king snake. I think GT's use the same switch for both headlights and fog lights, right?

There's a switch that turns the fog lights on and off completely, and the fog lights turn off when you turn on the high beams.

At worst you need to wire up another relay and maybe a switch (if you want one). At best Ford did what they did with non-power seat Mustangs... Wired them all the same way, just didn't install a power seat. So if you don't have power seats, but want them: call Stang parts, bolt it in, plug it in to the connector that's already there, and you're done.

Unfortantly, I think this is an "at worst" (which isn't all that bad at all) case. Of course you could do what the Pony God intended for the fog light holes: Vent the front brakes!

Or you can use the passenger side foglight hole and route a ram air system to the air filter. That's what I did on my mustang when I had it.

Use seperate wiring and switch for your foglights.

I don't know about them turning off w/the high beams on, I've never checked that, but from the factory, they are wired so that they can't be on w/o the headlights also on. Mine are actually wired through the power top so that they're independent of the headlights per www.mustangworld.com You might want to check for that wiring as well, but my guess is that it's more likely that the fog light wires are there instead of convertible top wires... anyway, good luck!

DOT regs require auxilary lights be powered only when headlights are on. That's only an issue for most of us when state safety inspectors look for that.

yes, the fog lights DO turn off when the high beams are turned on. That's how they are wired up from the factory. BUT, there is a fix for that.

Check for yourself. Turn on your fog lights and then turn on the high beams and look at the front of the car.
