Q: Fuel pressure test leaks

My GMC had leaking gaskets, so I replaced them by removing the upper and lower intake manifolds. I had some fuel pressure bleed down, so I replaced the injectors, fuel pressure regulator and fuel rail. Now I have the lower intake manifold bolted in and the new pressure regulator rail and injectors installed. I attached the connectors to the injectors, but I didn't connect the droves of other connectors, because I'm only half done with this job. Before I do any more assembly and fixing, I want to do a fuel pressure test to check for leaks. I will have to do this test without the fuel pump as the manual directs. My fuel pump isn't working right now because so many things are disassembled. Do you know which connectors need to be attached to make this build pressure? I need to check for leaks first.
