Need help identifying harness

So I got a little presumptuous and thought I'd start in on my harness after spending some time on lt1swap.com. Seemed simple enough that even my idiot self could do it. I think I was wrong. I have the blue and green connectors and was following his directions on which wires to pull out and get rid of. This is my issue:

I have this harness:



But trying to follow lt1swap.com's directions most of the harnesses have these style plugs:

Re: Need help identifying harness

Sure your looking at the right side of the connection? Gm harnesses have C, J, and X designation on harness headers like that. Depending on the donor, you may have an X header/plug, but be referencing the diagram from a vehicle using a J header. We went through this on a fellow members LS3 swap.
