plug and play it says. However, to mount the headlights to the 2000 Blazer mounting bracket you will need to remove material from the body of the new headlight (it won't be noticeable when you're done if you do it right). If you know how to use a Dremel and have a flat sander you can do it, but otherwise you're out of luck. Also, the jack you need for wiring is half the size of the original. You need to cut the original and put it on one. If all this doesn't bother you, it fits in the usual holder and has a factory fit when it's finished. Definitely not plug and play as advertised (perhaps on a Suburban, but not on a Blazer). Just be aware that you will need to modify the 2000 blazer and I suspect other blazers. but I know it will take some work for 2000.
