Should my fog lights turn on with the parking lights only or do the headlights need to be on as well? If only with the headlights is there a mod to get them to turn on with the fogs?

 

You can wire them anyway you want.

Factory usually wires them when the ignition is in position II then they are able to be turn on.

 

There is a mod called "fog light mod 2.0" in this forum, Search for it for full control of the fog lights.

OEM Setup: Fogs will only turn on with Low Beams, Turn off with High Beams.

 

legally- thats all they are allowed to do- on with low beams
Anything else is a separate switch you installed~

note driving with fog lights only can get you a chat with the local LE
BUT having white LED strip lights under the bumper/lights, is considered good form~
Go Figure!

 

There is a video on youtube on how to wire the fog lights with the parking lights
