Where does it say to follow "Tradition" not yet invented?

Stupid formulation. "Tradition" is capital-T Tradition because it is something in existence since Apostolic times rather than invented. There are other traditions that get formed and replaced by others in any society, such as the use of certain calendar fasts, lives of the saints, and ways of worship, but they are not a part of the Sacred Tradition delivered to the Apostles, preserved by the Church, and expressed partly in the canonized Holy Scripture. Protestants have traditions like that too.

You probably meant to ask, "where does the scripture say to follow the living magisterium of the Church"? The living magisterium is the teaching power of the Catholic clergy from the pope down to deacons, that is done in the single Catholic voice of the Church. It is, of course possible for any member of the clergy to say something from himself that is not inerrant and not a part of the Magisterium. An example of the magistarial teaching is the Church teaching against abortion, euthanasia, human cloning and gay "marriage", -- all but the abortion have no explicit treatment in the Tradition (and none are treated in the scripture expressly) since they are new phenomena.

Well, that mandate to teach ont he issues of the day by living people is reflected in the scripture. It is, in fact expressly authorized by the scripture:

[17] And if he will not hear them: tell the church. And if he will not hear the church, let him be to thee as the heathen and publican. [18] Amen I say to you, whatsoever you shall bind upon earth, shall be bound also in heaven; and whatsoever you shall loose upon earth, shall be loosed also in heaven. (Matthew 18)
[25] These things have I spoken to you, abiding with you. [26] But the Paraclete, the Holy Ghost, whom the Father will send in my name, he will teach you all things, and bring all things to your mind, whatsoever I shall have said to you. (John 14)
