I believe you are referring to the graphic I attached to this page that has both wire colors you mentioned.

The blue wire would be the brake output circuit that comes from the trailer connector. The black wires represent the leads for the brake magnets of the assemblies themselves. So both wire colors do connect to each other.

Some trailers may need an auxiliary power source to power additional 12 volt items on the trailer but this isn't as common as you might think. Now instead of aux power reverse lights are more common on vehicle side trailer connectors (and still…
