No spark/fuel

[KyleW707]

Car is a 94 camaro z28 bought as a roller. Engine, trans, and harness are from a 95 trans am. Everything worked while engine was in the trans am. Put everything into the camaro and now I am getting no spark, or fuel. I seem to not be getting power to the pcm (all grounds are good). Engine harness has both c100 and c105 connectors, but the cars body harness does not seem to have the c105 connector, as pictured. As I understand it, c105 has a wire thats involved with the ignition switch. Is this my issue? And if so, what is the easiest way to fix it? I still have the 95 trans am, should I take the body harness wires from it, and transfer to the camaro, or is there an easier way?
