I have attached a diagram for you to check out. This is taken from a helpful article on our site about wiring that I have linked for you as well.

The Blue wire on the diagram is what you want to pay special attention to. If you can route it through a tube for more protect then that's what I recommend doing.

The wire that should be used for the trailer brakes needs to be 10 Gauge Wire # 10-1-1. You can use Butt Connectors # DW05745-5 to make your connections. Simply splice 2 ends of the Blue wire together in one wend to branch off for the brakes on the other side of the trailer.

You can get a sample of what this looks like by starting at the 4:30 mark in the linked video. Please note that he is using Jacketed 2-Wire # 12-2-1 in the video.
