Jarv,
I think on yours, you need a 4mm socket. There are two little 'stem' looking things sticking up directly behind the headlights (One on each light) On yours, I believe turning them counterclockwise lowers them. Not sure tho'. Go somewhere that you can park about 25 ft. from a wall. With the lights on, you can try it in either direction and see which way it needs to go. 1/2 turn is noticeable. Supposedly, (from what i can remember) measure the height of the center of your headlight to the ground. At 25ft, the top of the beam on the wall is supposed to be at that same measurement. Also, along with the heavy gage wire harnesses....Aldive, and others are correct. The hard core stereo guys have known for years about how larger diameter cables (Even if only ground wires) give cleaner, more powerful sound. The heavier the wire, the easier current can flow thru' them. (Think 'water pipe') You would be surprised at how brite the stockers are with a proper adjustment and the addition of heavy (not smaller than 16.) gage wires. I just added a 12g. ground from my Batt. - terminal, to the engine block, and another one from the alternator chassis to the body to improve the grounding. Now, some tuners claim thier engines actually run better...I wont go that far without proof (Altho' Jacobs and others sell alot of heavier spark plug wire sets to get more power to the plugs) but, I do believe my lights are a little brighter, and the dash lights were noticeably brighter. I HATED driving at night in the Ex. until I re-aimed the lights and added the heavier wires.....

PS...I bet those S.S.'s are white as heck with the heavy harness!
