I love those junction boxes, it makes trouble shooting wiring a lot easier.
For trailers with 4 electric brakes the wire gauge size is sometimes just adequate.
Ours ran one wire from the 7 way to the LF brake, on to the LR brake, crossed over to the RR then ended at the RF.
I ran a larger gauge wire for each brake from the post in the junction box to each brake.
Now if I want to test a particular brake I can pull its' wire for testing and I know each brake is getting a good voltage.
