That connector if it is gray and has one wire needs to plug Into your knock sensor on the block. It's gonna be a b1tch because it's the one that's between the transmission housing and the motor. As far as the cam sensor, make sure it's plugged in and mounted poperly in the timing case cover. Did you make sure the cam magnet was still in the cam sprocket and all the dots on the sprockets were lined up properly before you put the housing back on?
