Hey Jeffrey.
Sweet, you have a Lippert 3,500lb axle. It looks like this axle already has a brake mounting flange installed. This is going to allow you to add all the braking components without replacing the axle. The parts you're going to need in order to add electric braking to the existing axle are as follows.
etrailer Electric Trailer Brakes # AKEBRK-35-SA. These are self-adjusting, 10" x 2-1/4" left and right for 4-bolt flanges.
Easy Grease Trailer Hub and Drum Assembly for 3.5K Axles - 10" - 5 on 4-1/2 # AKHD-545-35-EZ-K. You're going to want two of these; they come individually.
10 Gauge Wire # 10-1-1. Needed to wire your new brake assemblies to the junction. Sold by the foot, need enough to reach the front of your trailer from the brakes.
Mounting Bolts and Hardware for 10" Brake Assemblies # BRKH10A. Very simply the hardware required to mount your brake assemblies to the mounting flanges.
etrailer Trailer Wiring 7-Way # e99011. This is going to give you the ability to tie in the brakes with your existing 4 or 5-way, giving you a 7 way to connect to your vehicle. You will need ring terminals to make your connections # 44-5356A.
Bright Way Trailer Breakaway Kit # 3802346. A simple breakaway kit includes everything you need to set it up.
Now, if you don't already have a brake controller, you will need one. There are many different options from in-cab to something like the Curt Echo, which plugs in-line with the vehicles 7-way. This is what's going to provide your new trailer brakes with power. If you have any further questions, don't hesitate to reach out.
