If your not to happy about attaching directly to your grill, what I have done in the past is modified the badge.
I remove any fixture from back of badge then glue a cable tie or two to the back of it. Then you can just tighten the cable ties around your grill! This is a good way of hiding the cable ties and also doesn't leave any damage to your grill (but obviously damages the badge!)
I will try to upload pics to explain myself better :rofl:
