Where do you turn when the Greek and KJV(TR) do not agree? Such as 1 John 5:7? The only Greek text to have that rendering, as far as I know, where all written in the 1500's.

"Majority text" or "minority readings"
It is also fallacious and hypocritical to suggest that just because the reading found in 1 John 5:7 is not "in the majority of texts" that it therefore cannot be legitimate, when the very men who are behind the ever-changing modern critical text admit that the true reading may be found in a few or even one manuscript.
Westcott and Hort, the very men who introduced the Critical Text methods found in the RV, ASV, NASB, NIV, themselves said: "A few documents are not, by reason of their paucity, appreciably less likely to be right than a multitude opposed to them" (Introduction to the Westcott-Hort Greek New Testament, 1881, p. 45)
J. K. Elliott, a modern textual critic comments on transcriptional probabilities: "By using criteria such as the above the critic may reach a conclusion in discussing textual variants and be able to say which variant is the original reading. However, it is legitimate to ask: can a reading be accepted as genuine if it is supported by only one ms.? There is no reason why an original reading should not have been preserved in only one ms. but obviously a reading can be accepted with greater confidence, when it has stronger support."
Even Kurt Aland says: "Theoretically, the original readings can be hidden in a single mss. thus standing alone against the rest of tradition," and Tasker has a similar comment: "The possibility must be left open that in some cases the true reading may have been preserved in only a few witnesses or even in a single relatively late witness." - The Effect of Recent Textual Criticism upon New Testament Studies," The Background of the New Testament and its Eschatology, ed. W. D. Davies and D. Daube (Cambridge: The Cambridge University Press, 1956)
Sure, there are a few minority readings in the King James Bible, but for every one in the KJB there are at least 20 minority readings found in the NASB, NIV, RSV, ESV and that is no exaggeration"
