No need to remove the grill. The connector was slightly larger than the opening in the grill but just gave it a little push to get it to pass through. Used a snake and additional wire to pull it down under the frame then back up, to the DRL harness.Looks good! Question on the grill lights: Were you able to route them around the enclosed AGS area, or did you need to pull the grill? I thought about about installing some of these, on initial inspection it looks like running the wires through the grill would interfere with the shutters.
