Passion fruit help needed

Our landscaper planted this passion fruit vine about 18 months ago. I’m sorry to say that I neglected it over the winter, and it grew straight up the right side of the frame and up onto the neighbour’s pergola. I recently pulled down the part on the pergola, but it was numerous vines tangled together, so I just kind of stuck it on top of the frame for now. I know I should have pruned it when it got to the top of the frame, and then trained vines horizontally. I was more successful at doing that over to the left. Now I’m not sure what to do with the right side. I don’t want to kill it, but obviously it needs to be tamed a bit. Thanks for any advice!
