Its not hard. You can easily google the wiring diagram. Probably the most important thing is to make sure you have a good ground. Your brakes are electric and use more power than just lights so you need to make sure the ground is good.
There are seven wires in your plug and your truck will need a brake controller if it doesn't already have one.
The Yellow/Green/Brown and White are your normal trailer lights, just like on any trailer.
If I remember right, the blue wire goes to your trailer brakes. There are two wires on your brakes, one is power, one is ground. I don't think it matters which way you wire it.
Then there should be a red wire. Thats a 12volt power feed from your truck. That can be used to maintain a charge on the emergency brake battery or power internal lights like on a box trailer.
The other wire, I forget the color, black maybe? Is for reverse lights. I like to put reverse lights on if I have room. Any wires you don't use, just cap off. It won't hurt anything.
You can find everything you need to know online. And you can buy complete brake kits that you just bolt on ready to go if you need to fix the brakes. In my state, any trailer over 3000 pounds or with multiple axles, has to have brakes and any trailer with brakes has to have an annual inspection. But that varies greatly from state to state.
I look forward to updates as you go!
