Tina, I hope your feeling better now.
I just wanted to post this pic so that you or anyone else can be more clear as to which way it goes on. the top part goes in alittle to a small V. the bottom part is rounded and smooth with no V. so when they are stepping into the harness , the part with the slight V is on the top, the smooth rounded part is on the bottom.
you can see it in this pic. the slight V part is on the top, smooth rounded part on the bottom
