Steve,
I've use a VX-2000 as a node radio. I don't know how close they are, lets hope close.
If I remember, the Discriminator can be brought out to the DB-9 by moving a zero ohm resistor on the board.
You will have to get a copy of the service manual to verify. I also remember using AF Mute as the COS / CTCSS signal. If you program the radio as CTCSS, AF Mute should track this.
No info on the VRX-9000, sorry.
Hope this helps.

Good Day! I am looking for proven working interface wiring and signal
trimming to interface a single URIx to two different radios. I need to
interface a cross-band repeater to a URIx. [I have two URIx's. If fully
connection two radios has advantages or is easier please explain.]
The receiver side is a Yaesu/Vertex VX 2100. I don't see a
discriminator out, so maybe just AF Out on pin 2. I don't see a
PL/CTCSS/COR/COS out, so manipulation of the RSSI on pin 5, maybe? It
looks like you can program some output general purpose pins on the
radio, but I have not found a list of those capabilities. Would
appreciate interconnect information from anyone using this radio with an
URIx.
The transmitter side is a Yeasu/Vertex VXR-9000. It has AF input on pin
3 and PL input on pin 4. The external PTT on pin 12 seems straight
forward. I would appreciate confirmation of a working interconnection
to a URIx.
All pointers appreciated.
