Downtheroad.. That wiring diagram IS messed up.
According to Dexter axle, the grounding of the brake magnets should not be done at the trailer frame.
Instead ALL of the grounds for the magnets MUST return to the CONNECTION at the tongue of the trailer.
This is important for proper brake operation.
For the OP, there will be a pair of wires running INSIDE the axle tubes.
The problem with this setup is the wire is free to move around inside the axle tube. This movement over time will break the wires or chafe the insulation to the point you get intermittent shorts in the wire.
If you are having any problems with the brake wiring, bypass the wires going through the axle tubes.
In some cases it is easier and faster to just run all new heavier wire from the tongue to the brake magnets. Doing so eliminates the subpar OEM wiring.
