That doesn't look 100% like the manifold, but yeah, it's pretty close. The Z4 swap post is pretty important, since it tells you which DISA wire goes to which DISA.
The biggest thing I'd say is to label every wire, since there's a group of four in the back (they're a bitch, by the way), and you want them in the proper order. Otherwise, it's pretty much "unbolt what you need to get at it, unbolt it, don't force anything, installation is the reverse of removal".
I have pictures of mine somewhere. I can probably get the up early next week, since I'll be hitting ACBF in Boston this weekend. Keep an eye out for a red 325 with Vermont plates.
