04 Engine part Tiburon GT v6 2.7
 

Does anyone know what this electrical plug is? Its on the side or the engine next to the aftermarket air filter. The mechanic who took it apart split town and his boss was putting it back together and this plug crumbled so he electric taped it in place but doesn't wanna release it till it has the proper plug.
