You can switch your trailer's 5-round to a 4-way flat with a couple of different parts. Start by replacing your trailer's 5-way with the 4-Pole Trailer End Connector # 18004.

Since you have separate brake and turn signals you will also need a converter to combine them in order to work with the 4-way. For this you will need the Curt 2-To-3-Wire Tail Light Converter # C56196.

I have added links to video reviews for you to check out as well.
