You do not want to mix aluminum with copper like found in the trailer connectors like # 50-67-103 as well as the trailer lights and brake magnets. The dissimilar metals will cause galvanic corrosion and can cause wire failure. I recommend instead using # 12-1-1 and # 16-1-1 sold by the foot for your wiring needs.
