Howdy and welcome to Airforums.com! You will get the answer to you question quickly, but unfortunately not from me (I have an older trailer).
This might be a good time to consider getting an Owner's Manual for your trailer, and perhaps even a Service Manual. Between them, those two books will answer many questions that you will certainly have.
Hang in there, someone will come along soon with your answer
