You don't even need the 'Y' (I think it'd be the wrong gender anyway)
- you can daisy-chain the AUX cable through the KAT500 to the KPA500.
You'll need a separate chain of RCA keying cables, unless you can work
the keying output from the Icom into your custom cable along with the
band data.

So you'd have your custom band-data cable, plus an RCA keying cable,
from the Icom to the KAT500, and a E850463, plus another RCA keying
cable, from the KAT500 to KPA500.
