Hi Jeff; the Curt 7-Way to 4-Way/5-Way Trailer Adapter # C35FR you were looking at will do a fine job. Really any adapter that has the built in resistors will do the trick. Curt makes good products so you can't go wrong with theirs. It also gives you the option to adapt to a 5-way if you need it at some point as an added bonus.
