where does the other end go? when i did my swap I had a wire hanging back there also I couldnt find out where it went so I left it hanging and car runs great, but it might be your crank angle sensor wire, jdm motors dont have this sensor I think. look on your old motor and see if there is a wire running to your crank and compare the connectors?
