To wire your trailer from scratch you should first start by, sketching a diagram of your wiring. That way if down the road there is some issues with your wiring, you're going to know exactly where to look. You're going to need to add a 4 flat # 002220, and a 7 way connector # ETBC7.

Next, you'll need to add rear lights # M880-7 if you do not have any currently.

Finally, for brakes, you'll need to first determine what the axle capacity is first. You can determine this by checking the axle tag located on the center of the beam. From here you can determine which brakes you need based off the axle capacity. For instance, if your trailer axle capacity is 2,000-lbs you can use the Electric Trailer Brake Kit # AKEBRK-2, with the hub and drum assembly # AKHD-545-2-EZ-1K.

I have attached our trailer brake selection you can choose from when your axle capacity is determined.
