Yes, you misunderstood the purpose of the question. 

The Yaesu Quadra provides a contact closure when the T-F Set button 
on the Quadra is pressed.  The T-F button causes the Quadra tuner 
to retune, etc. if it is pressed and the amplifier gets at least 
75 Watts drive. 

If the K3's "Key" (straight key) input were active in data modes, 
the T-F output from the Quadra could be connected to the Key 
jack and the K3/Quadra interaction would be fully automatic (if 
one used the N0SS designed cable) just as it is with any of the 
Yaesu transceivers.  

Unfortunately, the K3 does not have an unused DigIn line that 
could be used as a dedicated "T-F input" but enabling the Key 
input in all remaining modes (Data, AM, and FM) would be an 
entirely satisfactory solution.  If closing that contact were 
to use "Tune PWR" in Data/AM/FM, it would be icing on the cake. 

By the way, for AM, FM and FSK one can connect T-F Set to BOTH 
Key and PTT using a pair of diodes but this still requires the 
user to switch modes to tune the Quadra when using audio based 
digital modes (AFSK, PSK, etc.).
