[Elecraft] RemoteRig and KPA-500

[Charles Stampf via Elecraft]

I'm having some fundamental issues understanding the cabling of the KPA-500 and the RemoteRig system.  Can anyone give me some pointers to get me started?  I cant figure out where to cable the amplifier as the ACC connector on the radio is occupied by the RemoteRig box. Is the additional wire to pin 8 on the KPA500 AUX connector still required when using the K3/0-Mini?

Thanks for any help.......
