Yes, the connections are as you've suggested. The KAT500 has access to the K3's band change lines, AUXBUS, and can interrupt the KPA500 PTT key line with just that one cable.
I have that same "too busy" ACC connector problem with antenna & bandpass filter switching, amp, PR-6, and PTT/FSK connection to a microHAM device. I'm using a couple of layers of Y connector, dislike the solution, and I have ideas to resolve that problem somehow. Unfortunately I have more ideas than time to implement them.

I have a pretty well stuffed plug on the K3 ACC socket now (RTTY interface / KRC2 / PR6 / KPA500). Does the K3 to KPA500 cable simply go to the KAT500, then a jumper from the KAT to the KPA ??
