8 step wiring

I finally found a 240sx so If the Ivan doesn;t blow my shit away this week I will ordering a rb25 clip. I was searching for wiring hook up being that is the only thing I think will give me trouble. I read about some 8 step something or other but cant actually find it please help with a link or something. I will be getting a GTS33 clip/LSD/axles and the mounts&shaft from Mckinney so if there is anything I am forgetting please tell me thanks.

I have since read bad things about flashoptions so I will probly be buying just a r33 clip.

What kind of bad things?

I've read about people getting clips in worse condition than advertised, not getting anything at all. But most are a friend of a friend stuff. so i dont know. a matter of fact I'm going to start a post about them right now.
