You take the long rod for your tire jack. There should be two ears on the end. Slide it through the hole, I believe it's just above the license plate. The hole resembles the rod and ears. Guide it through to the spare tire mount. There is a fitting that the handle ears fit into. Put the handle on the other end and crank the spare down. (Hint) If you can reach spray the fitting and chain with WD40. Some times the unit can get pretty cruded up.
