unscrew 3 bolts from behind the mirror, unplug it and take it off. Put the new ones on the same way. If it doesn't have a harness, cut the factory harness (leaving enough room to put it back on later if you need) and solder the wires together. There should be an extra wire for the LED's. If you are wiring it to the blinkers, just splice them in, or you can wire them to whatever you want. It is really easy.
