I actually tried to install the OEM kit ones first. They're kind of a pain if you don't know what your doing. I really didn't know what I was doing lol. Anyway, if you get a OEM kit ik it requires you to take a bunch of wiring harnesses out of your fusebox to insert the new wires for the fogs, and bring it to the dealership after for a Starscan update. If you get a good deal at a dealership to install and order them that might be a good idea. Otherwise you can hook em up like I did and just hook them up to a simple toggle switch. Only thing is I never hooked the OEM wiring harness up to a toggle so I'm kinda fuzzy on how to do it. I bought a pair of housings with no kit or anything and put in some leftover HIDs that I had. Although I'd be glad to offer any advise I can with wiring. Electricuted myself enough that I think I got the hang of it
