First take off the grille. There were two screws on the top and two on the bottom of mine.
Once the grille is out figure out where you want the signals. I wanted them as far out as possible so I put them in the far corners. I took a pair of pliers and crimped the top and bottom of the grille to make a little more room. After I did this I figured out I might not have had to since the vertical supports are actually what hold the light in the grille.
Here's the light location for mine with the grille out. I used a Dremel to grind out the outer edge of the vertical support to allow the two pieces of the light to grab the grille to hold the light in place.
Next comes the actual wiring. You'll only need the black and blue wires here since the yellow wire is for the parking lights. I suppose you could try to add in another bulb but for me the only thing I needed was the signal. Connect the blue wire to the wire in the light and the black wire to the ground plate in the light. I had to add a bolt and nut to connect the ground. I soldered the blue wire to the light wire and used electrical tape with everything to be housed inside the light.
When you've got everything wired up put the orange transparent lens in the front of the grille and the back plate behind the grille, thus using the grille for the meat in the sandwich. That's it!
Here is the end result.
