Battery Connection Help Please 806

[Slowtriathlete]

Hello,

I just got my first trailer, a used 2007 Jayco Jay Series 806.

Unfortunately the battery was disconnected by me until we went on our first trip. Normally I would have taken a pic or taped to identify locations...but alas I did not.

I have 3 connectors to go to the battery...

-1 red large with 30amp fuse within the connector.
-1 white large
-1 thinner black and orangey type colour

White traces to connection on trailer frame, making it the ground I think. Therefore goes to the negative.
Red I am guessing is power and positive.
But where does the other go? +/-

Thanks for any help you can offer

The black wire is probably the break-a-way switch for the brakes and is a + connection if you have electric brakes.

Thanks very much.
