    Welcome! I think that one you open hood and reach in from back of headlight(behind rad support). 1/4 twist and pull out. Try not to touch new bulb with your finger tips. Use a clean rag or paper towel as not to get oil from your skin on bulb it will cause hot spot and blow bulb prematurely.

    I ordered a set of Sylvania Ultras for my 1995 and 2001. I can only see one of the plugs for a bulb when the hood is up. When they come in I will post on how it is done. I have a shop manual that I sincerly hope shows me how to get to the high beam bulbs.
