Well, I found a connector on the right headlight that had a plastic cover over it. I am hoping it would be the fog light connector. Do I have to buy a fuse for the fog lights or should everything already be installed and ready to just install the wiring and lights? I would appreciate any help on this. Thanks. I have a 2006 GMC Sierra 2500 HD.

 

Use a relay so you dont overload that circuit. If that happens, the fuse will pop and you will have no headlamps.
