Plug and play. If you google around, there are you tube descriptions on how to change the fog lites. Just have to know how to "pinch" that connector. Be sure and NOTE which way the little notches faced - up or down - you will see these on your new bulbs. There is like one notch on one side and two on the other ?
Be sure to plug the connector back like it was, first time I plugged it backwards, and this makes them blink....you don't want blinking blue lights (blue is illegal, but, no one has messed with me so far - I had them on my Harley for years, no issues - but you don't want them blinking)...AND, if you drink and drive or any "other illegal activities" probably not a good idea to have blue lites on...blinking or not. Fortunately you can turn these "only" off or on at will....at least on my car.
they are tricky to get to. (2014 RT), the drivers side, un did the 3 - 4 pop out fasteners, had to turn wheel all way to left, then use cell phone to "video up in there"....you wont be able to see what you are doing. Drivers side is hardest, took me 20-25 minutes. Then turn the wheel to the right for passengers side, that one took me 10 minutes. Passengers side is a little easier, plus I had experience by then.
I have pics and video on my phone, but, they just don't do it justice....they look far better in real life.
