Stand it up on its end, lining up the holes to the wires. Slide into holes and 'flip'/rotate white plastic piece down into a flat position.

This was absolutely wonderful instruction. Great detail. For separating the glass at the end, just warm the frame around the seam where the glass is glued down with a hair dryer on hot setting and use metal tool to pry around (see you tube videos ) you may have to re-heat if it takes a while. Couldn't have done it without these great instructions. Saved me 200.00. Thanks!
