Hey Jason,

I did some research and it looks like that trailer has a 3500lb axle. For electric brakes I recommend # AKEBRK-35-SA. This is a left and right hand assembly ready to slide on and add those to your axle. For the hub and drum assembly I would need to know your bolt pattern in order to find the right size one. I have attached an article for you that shows how to accurately measure your bolt pattern so we can find those parts for you.

Let me know your bolt pattern and I will get the hub and drums sent over too. Are you going to be needing a brake controller as well?

@JasonK Thank you for getting me that information. The hub and drum assembly you will need is # AKHD-545-35-EZ-K. Those do come pre greased so they are ready to just slip on and bolt down.

Yes it makes sense and it is possible to just use a junction box with pre-installed 7-Way to connect your 91 Tundra with 7-way to the 4 flat on your trailer. I recommend Epicord 7-Way Molded Trailer Plug With Junction box part #277-000141. The molded…
