I have a 2007 F-150 need help with the wiring harness. I would like to add factory fog lights it did not come with them I just need to know if the wiring in the truck has to be replaced just to install fog light

 

Are you going to try and hook them up to your factory wiring to come on with the headlights? That im not sure of, if it were me ide just hook them up directly and use a toggle switch hidden somewhere in the cab. They're an auxiliary light if you ask me anyways, you dont always use them so they need they're own switch. Try reposting in the electrical forums.

 

I am trying to stay with the stock look b/c this is my first truck ever

 

all you should need is the factory harness for the fog light and the the stock headlight switch that has the fog light provision.
