I did a fog mod. (Fog lights can be on without the headlight on) first, so the fog wiring is actually connected to the wiring of sidemarkers. If I wanted to do a HID conversion on the fog, will those wires hold? I know it might not be a smart question, but if you have done it, please let me know. Thanks.

 

u should use that for that wire for the relay trigger.. .then use the relay to switch on the ballasts.....
