The output circuit of a trailer brake controller like the Tekonsha Voyager # 39510 will need a wire no smaller than 10-gauge, such as # 10-1-1, to deliver full output voltage to the trailer's brake circuit.

Since you have about a 4-1/2 meter distance (14.85-feet) you should be fine using 10-gauge. But if you want to err on the side of caution you could always double up the wire run with tandem 10-gauge wires or use 8-gauge wire, although I doubt this will be necessary.
