Is there anyway to make your fog lights stay on with the high beams? I know in other carsI had, there was a simple wire job done with the relays and it would make the fogs stay on all the time. Just wondering if anyone figured this out with the newer mustangs yet?

I'm curious also. I had an F-150 before the mustang and it was just a jumper wire on the relay. It might be the same for this car, but I'm not gonna be the guinea pig.

 

FYI, that's illegal.

 

Yea its illegal but its only meant to put more light on the road when its very dark and no other cars around. Also the switch still works to shut down the foglights manually if you dont want them on with the high beams.

 

Where is it illegal?
If so wouldn't all the after market fog light kits (I've installed aleast 6) have a warning on the box stating "you can get fined or face jail time for running around with hi-beams and fogs illuminated"?
I can't imagine a Cop seeing a car running both sets, and thinking "I'm gonna bust someone who disabled the autoswitching system the factory delivered on his car", but saying oh well that other guy has aJCWhitney kit with no auto switching so he's ok.
My rant for the day....

 

So is there a way out there? Whether it's illegal or not, I've done it on all my cars and never had a problem.

 

This is a link of how to do it to an F-150. The wiring most likely is the same for the headlight and foglights as our Mustangs. The only thing that probably is different is the location of the relay. But if you find the relay that controls the lights you might be able to follow these steps and do it.
I HAVE NOT TRIED THIS ON THE MUSTANG DO SO AT YOUR OWN RISK.
Hope this helps

Okay, I'll take a look at it and see what I can come up with. If anyone knows of a forsure way of doing this, please chime in!
