Question about connecting to an existing fence

I've tried to find answers on this for days, but Google search is unfortunately very unhelpful.
I have a 6 acre lot that I'm trying to surround with an electrical fence so that I can do some rotational grazing. The south edge of my property already has a barbed wire fence on it that I share with a neighbor. The east edge has no fence at all. It meets that southern fence right about in the middle. In order to build my fence, I'm going to have to attach it somehow to my neighbor's barb wire fence. I have an idea on how to make this work, but I cannot for the life of me find any information on how to add an H brace in the middle of an already existing barbed wire fence.

Specifically, I'm trying to figure out if I need to build a 3 way brace (shaped like a giant T looking down from the top) with two sides connecting the cut ends of my neighbor's fence, or if I can simply put a 90 degree corner brace there and connect my neighbor's fence to either side of that brace.

Neighbor is OK with me doing the work, I just want to make sure I'm going to do this right before I start mucking around with his nice fence line. Has anyone done this kind of thing before? I'm 100% a novice at fence building, so I want to learn as much as possible before I start working.

Assuming you are attaching your fence to your neighbors singular wooden fence post, you will need to install a T-brace, and install three fence posts. You will need one eight feet to the right from his installed post, then another eight feet to the left of his installed post, and then one eight feet in front of his fence where you want your fence to go.

Install your rails using a drill and pins

Then to brace it with wire you need to use daisy wheels...you have to use these because you cannot use winding sticks on an already built fence because there is no room to swing the winding stick up. But a daisy wheel can be ratcheted in. They are used to tighten electrical fencing and have a detachable handle to crank them, fortunately they are cheap.

Either way you always want to remember you anchor your line to the ground. So you want to run your bracing wires from the top of your neighbors existing post, to your newly added post to the left and right. Again, top of the existing post, down to ground level with your new one. But its different on the one going to your new fence. You want that brace to go from the top of your post to the bottom of your neighbors existing post. But then also from the top of his existing post, to the bottom of yours, so this one needs to by x shaped with bracing wire. It has to be that way because you are bracing your newly formed corner, but also holding tension on your new fence.

With this arrangement you will be amazed at how rock solid your corner is. And your neighbor will be impressed you built it right!

PS: Buy 10 foot rails. Your posts might not be plumb so if you place them 8 feet away, and you buy 10 foot posts, you can cut your posts to fit.

Thank you very much, this was exactly what I needed to know. Neighbor doesn't have any wood fence posts, the existing fence is just barbed wire on T-posts. I'm assuming that if that's the case I should install a wood fence post right where I'm joining the two fences together so that the braces will be stable (since I can't brace a wood fence post to a t-post). Then I can build out the whole T brace as you described.

With the bracing wires, I'm assuming I need to install them that way so that the center post of the T is being pulled from the top in all directions by the bracing wire in order to prevent the tension in the fence pulling it over / heaving it out of the ground. The extra wire on my side is to prevent my fence from pulling the center post over. Do I have that about right?

Yes, that is exactly it.

Think of it like a tug of war with a rope. Both sides always leans back away from the pull, but why?

To counteract the tension of the opposing team.

A fence is the same way, always in tension so the ends want to be anchored to the ground. Your bracing wires is what does this.
