First you have to remove one Phillips screw from the back of the light assembly and remove the back light cover to get to the bulb socket. The H6M bulbs have only 1 locating tab on the ring around the bulb. The stock bulb has 3, and can only go in 1 way. The only trick is when you twist and unlock the stock bulb from the housing and remove the stock bulb from the socket you have to figure out which slot the single tab on the H6M bulb must go in. Of course you have 3 choices. By looking close you can figure it out by seeing were the 2 bulb contacts will line up with the contacts in the socket. You then have to kind of hold the H6M bulb in place as you put the socket back in the housing. It will feel like the bulb will be loose and not stay in tight, but when you lock the socket back in the bulb will be tight and stay in place just fine. Then you need to check it by turning on the lights and see if they light up and the high beam and low beam work correctly. If not you need to remove the H6M bulb again and put the tab in a different slot until everything works correctly. It is really not that hard to do and is well worth the effort. The H6M bulbs are much brighter than the stock ones and you will notice a big difference. I compared mine by changing one bulb and then turn on the lights and compare the difference. You will notice it right away. If you need any further help please contact me.
