I've linked an article on trailer wiring that includes a diagram you might find helpful.
One solution to help wire everything together is to use a junction box with your trailer's 7-way connector, like # 277-000141. This way you can run all of your trailer's wires to the box instead of to the back of the connector.
To wire you brakes you'll want to use 10 gauge wiring # 10-1-1. For the lights you can use 16 gauge, # 16-1-1. Both are sold by the foot.
When looking into the back of the trailer's 7-way you'll want the wires run to the following pins:
Reverse Lights - Center pin
Right Turn and Right Brake Light - 3 O'clock pin
Brake Output - 5 O'clock pin
Ground - 7 O'clock pin
Left Turn and Left Brake Light - 9 O'clock pin
Running and Tail Lights - 11 O'clock pin
