G'day, All I do is common the individual power leads to the K2 and external KPA/KAT at the power supply. Seems the simplest thing to do and ensures the correct power up sequence. No diodes required, no voltage drop on the KPA lead passed through to K2. Things can be made too complicated, KISS rules.
