Through the hard cover369 viewsJust an FYI: I do NOT recommend this method! PITA if you have any issues. Go through the rubber cover.
Make a template that is 7/8" in diameter and trace with a permanent marker. Or put a nail or screw into the center of the circle and tap it so it leaves a dimple -- that's where you will drill. I used this location because it gave me the most slack in the wiring. The shop that does this recommended not putting the gasket in the center of the hard cover because there wouldn't be enough wiring slack.

Right side368 viewsThis is the side I started on and passed the harness through the hard cover as recommended by a shop that does the procedure. What a MAJOR pain in the butt! Ideally, it would be best to REMOVE the airbox in order to get enough space to maneuver around; a much bigger task than I cared to do after 3 hours of work involved already! I have long thin fingers and trying to get the bulb in the socket, as well as the gasket into the hard cover, was quite difficult. Anyone with thicker and/or shorter fingers would likely have an even more difficult time as the space is just too cramped around that area.

360 viewsThe original bulbs came with a plastic ring to help hold them in their shipping case. I split it and put it behind the bulb, then carefully pushed the bulb retaining tangs onto the plastic ring. This kept the tangs more even. Without them you'll need to push the tangs down a little bit as well as bend them inward in order to retain the bulb. I oriented the bulb just like the halogen it replaced, tab pointing up. No shadows were cast, full light is output.

358 viewsWhatever plug you may have, simply push the connectors into the gap on the inward side of the light housing as this has a good gap to hold it out of the way.

344 viewsI used the supplied double-sided tape to mount the electronics under the cosmetic cover. If you do this make sure you clean the mounting surfaces with rubbing (isopropyl) alcohol.

342 views...use a hole saw or reamer to enlarge to 7/8" diameter. This is where the gasket will mount and allow the wires to pass through.
