Have you checked for 12-volts on the power feeds? I would make sure you have a full 12volts on each, and also verify the ground is good. If you have a 12-volt test light or multimeter.
Something I just noticed on both of these wiring diagrams is this ground, it almost looks like the old radio had some type of case ground, is there a Black wire from the old radio harness in the connector there? It looks out of place on these diagrams.
