Thanks Gordon...
The rain stopped just after I posted and I went out to investigate...
I had to take the whole fuse panel and 12V converter out to get into the area but I was able to track them down. They both go to the same ground bus bar under the fridge..
I guess they wrap to the outside of the frame to make it easier to maintain them? The trailer is less then a year old. Thats a lot of corrosion for the self tapper they were on to lose its head. Oh well. I did wire brush them and re-install on the inside of the frame so they are not as exposed to the elements.
Overall I am not to impressed with the build quality of this trailer. My 2015 Starcraft that we replaced seemed to have a lot more attention to details. Still not built great but just a little better fit and finish.
Again much appreciate you taking the time!
Mike
