You mean a "Front End Bra". Don't worry about which hole, or how many holes. Just take the strap and put the hook into either hole or anything else that will keep hold of the hook and then tighten down the strap by pulling on the cord till it's tight. Do that with both straps so the bra is snug.
Suggestion. Don't use the bra all the time. Don't let it get wet. Put a good coat of wax on the front of the car and hood before putting on the bra.
