Does it matter which way trailer brakes are wired?
The brakes are not grounded, so the wires coming out of the back of the brakes does not have polarity ( no hot or ground).

How big of a wire do I need for trailer brakes?
Another way is to have an adapter that goes from the trailer 5-pin to a standard 7-pin (with 2 wires left blank). That way the trailer brakes are ready, if the tow vehicle has a 7-pin connector. Size: Don’t skimp on wire size for your brakes. For a single axle, 14 gage is good, but for tandem axles, use 12 gage wire.
Why does my truck say service trailer brake system?

What are the different wires in a trailer?
Only the (blue) brake and (white) ground wires are different. You can expand the same conditions for more axles. Use only the needed wires, and ignore the others. For example, if you don’t need Auxiliary Power, just leave it out. If the axles do not have brakes, then no need for that.
