So I want to tee into the main line of my irrigation to add a hose spigot. I have attached some photos...where is the best place to tap into this line? This is in an area of the yard where I'm honestly not picky. It could be in the area I dug up or even to the left of the control box you can see in the picture.

I think it makes little difference if it's before or after the shut-off valve (which is in the green box) since I've never shut this valve off and this hose won't be used constantly, so it's just a matter of finding someplace easy to tap into this.

I am somewhat handy, but inexperienced with irrigation issues like this. Any suggestions?
