On the outside-facing portion of the shifter, there is a small recess just forward of the beginning of the hood, about halfway up the plastic between the shift lever itself and the hood. Insert your 5 mm allen key into that hole and you'll find a bolt buried back there-you may need to hold the hood back a little to get the key in there well.
Sorry for the vague description but that is the best I can do for now without a picture, and I just don't have time for that at the moment. Hopefully this gets you started.
