Thank You ALL, for talking about wiring of brakes... as last fall dealer replaced all brakes on my New to Me Trailer.. never gave it a thought on wiring.
went under trailer this morning... and to my surprise ...
there were 2 butt connectors for each wire of 4 brakes.. and 4 wire nuts from Main brake wire to smaller wires going to backing plates..
so I removed 8 butt connectors and 4 wire nuts... and soldered everything..
the Main brake wire is 12 gauge from 7 pin plug to left side axles.
will figure out what I need to change to the Star setup.. as main wires is fine .
so timing is great... as we depart on a 5,000 mile, 5 month trip soon.
