Question:
I finally got a decent day to coincide with a day off so I started to install the electric brakes I ordered from etrailer. Everything was going fine until I went to put the brake unit on the axle. Was the kit supposed to come with nuts for the backside? I've attached pictures of what I'm taking about.

Since we know you have 3,500 lb axles we can pretty easily pick out the correct parts you'd need to add brakes to your trailer. You'd need new hubs that have integrated drums like with the part # AKHD-545-35-EZ-K which have the very common 5 on 4-1/2 inch bolt pattern. Then you'd need to add matching brake assemblies with the part # AKEBRK-35-SA and you'd be set aside from 10 gauge wiring like part # 10-1-1 which we offer that you'd want to wire up the assemblies with. This is sold by the foot.

Thanks, I picked up the nuts locally. I got everything installed except for the wiring. There are wires on the utility trailer that run front to back. I thought I was supposed to run one of the brake wires to the frame for ground and attach the other to the blue brake wire but when I dug more into researching how to connect I started second guessing it. Is there a clear tutorial for a situation like mine where I am adding electric brakes where there were none before? Thanks again!!!
