wiring ?? what are these plugs

[Gunny Davis]

can anyone help me with these plugs and the pinouts I will need to wire in my project.
I have taken a 5.3 Vortec/ 4l60e from a 99 Silverado and am putting them in my 72 Blazer. I am finaly to the point where I need to get the wireing together. I have the complete harness, computer, cruise controll module, and fuse block.
I have seen the pinouts on a couple of sites but I am trying to incorprate the fuse block too. Can this be done?
Where can i find something that identifies the block plugs that connect to the bottem of the Under hood Fuse Block?
