Slimshady's instructions tell you to remove the tabs from the PIAA's, but you don't have to. Simply mount the housing up-side down and be sure to flip the lens so that "PIAA" will be right-side up when they're mounted.
Instead of using a dremel tool to remove the excess plastic from the factory mounting brackets, I simply took each bracket over to my oscillating spindle sander (from my woodworking habit) and sanded off the excess in no time flat.
To make the lights easily adjustable, I made a rubber washer to fit between the factory bracket and the PIAA housing on each screw. I made the washers by cutting 1/8" or thinner pieces off the end of some vaccuum hose. Works like a champ!
To connect the wires, I cut off the connectors and about 3" of wire, from the PIAA harness. I spliced those wires to the factory wires with "Quick Connect" connectors. I didn't even have to remove the factory connectors! (Just be sure to tape up the connectors so there's no chance of a short later on.)
Re-installaion was pretty easy and with the added rubber washers, adjustment is simple: push the light up or down as required. The rubber washer maintains enough tension to keep the light in place.
