The DIN connector has 4 active pins it seems - plus and minus power, a 
signal that should trigger the transceiver if you press the tune button 
to trigger the radio to make RF, and a signal that indicates the tuning 
process is complete.

None of the indication signals directly interface with the K3.

As others already said, I don't think the K3 has an interface for either 
of these signals. The procedure would then be:
1. reduce output power on K3
2. press TUNE on K2 to start generating RF
3. Press TUNE on tuner to make it start a tune cycle
4. Tuner will indicate completion of cycle
5. Press TUNE to stop K2 generating power.
6. Restore RF power setting.

There is no integration between the K3 and the Z100A unfortunately.

LDG makes many tuner models, some actually talk to the radio to do part 
of the above process automatically.

My suggestion is to join the LDG group at
