Wife put a large dent in my 2019 RAM 3500 Laramie Megacab year or so ago. Ugh. Finally ordered a replacement OEM bumper from eBay, which was slightly different on the backside and had the hole shown by the arrow in the pic. There's a small pig tail behind it, but I can't seem to find what it's for. My old bumper was solid. The "cap" shown in the bottom pic did not come with it. Appreciate any insight. I'm thinking another LED light of some sort is in order.
