The wiring diagram you posted in your first post above matches the 2003 Matrix wiring diagram. I also have an official paper service manual for a 2003 Pontiac Vibe, and the connections for the crank and cam sensors match the diagram above. Connector "A", with cam between pins 26 & 34, crank between 27 & 34
However, I found a Toyota Matrix wiring diagram for 2004-2007 at cardiagn.com and its different

shows crank between pins 25 & 33, cam between 24 & 33, but on connector B
Your picture shows no wires on pins 25, 26, or 33 for connector "A" . Also, both Toyota diagrams and my Vibe diagram indicate that the common return for the sensors is a white wire, and the other wire for each sensor is black.
Maybe its different between the 03's and 04-07's Does it look like there's black wires in pins 24 & 25 in the wire bundle for what your pin number diagram calls "E4"?
