I have not looked, but is there a harness laying around the foglight location on an 04 Mustang for the foglights? I am looking to install foglights on my Mustang, basically just wondering what any of you guys did as far as wiring goes. I am debating just wiring them up to the headlight circuit.

 

v6mustangstuff has a wiring/relay and switch kit for 100 bux. i just got mine but havnt installed them yet. ive heard they are a piece of cake. if u already have a switch for the lights then they are prob already wired up. really, if u have the simple know how then u should be able to buy a realay, switch, and wires from a home improvement store and buy ur own stuff.
