I am waiting on the box to put a battery in to come in
That told me a lot. Thanks
Now what I would do is trace the #4 wire from the trailer plug back into the trailer and see where it is attached.
At this point I would think it attaches to obviously a Positive DC point in the trailer.
My guesses this wire can be attached someplace where the Positive battery cable is located on the trailer.
It goes all the way back to your DC battery circuit breaker panel inside.
That is the best I can tell you at the moment.
I will do some more research and see if I can find out where it goes by searching the web.
