[Elecraft] KPA500 + KPAK3AUX

[Franki ON5ZO]

Just checking as I'm about to lay my hands on a 2nd hand KPA500.
I'd like the amp to follow my K3 so I need the KPAK3AUX cable. However the 
AUX DB15 on the K3 is already in use for my microHAM SO2R controller.

Am I correct in assuming that by using the supplied Y-cable in the KPAK3AUX 
kit, the amp and K3 will talk to eachother and that my m/H MK2R+ will keep 
on working as it does?
That would be really 'neato'  ;o)
