in the first pic you have disconnected one of the 3 pin diagnostic connectors, but you have only removed it from its holder so that cant have any effect.
in the second pic i cant see the lambda sensor connector. it should have 3 wires on the connector, and the wiring to the right of the connector should go down to the exhaust. you dont seem to have it there
