If you put an automatic engine into a 5-speed car, then it's the cup that holds the Crank Positioning sensor, located just under the exhaust manifold. It is a bitch to change though, because you have to separate the engine and transmission to get to it. After you do that, its just one little screw that holds it in place. The head of this screw is just inside where the transmission meets the engine, which is why you must separate them.
The reason your car won't start with the sensor housing that you have is the ring gear. The CPS (crank positioning sensor) is supposed to get magnetic impulses from the ring gear. However, an automatic transmission has a larger ring gear, so the CPS faces straight towards the driver side fender. However, the 5-speed's smaller ring gear calls for the CPS housing to point the sensor more towards the driver.
To sum it up, your current CPS is facing like this [ --- ]
However, it is supposed to be facing more like this [ / ]
