Pretty good chance you can't. Typically the CG encoder is in the TX compartment. You'll need to run a shielded line from an unused terminal on the door to your external encoder and jumper that terminal to the CG input of the exciter.

Good place to inject CTCSS in to the Mastr2 control shelf from the TP-3200 panel?

PTT from the 3200 would go to the CTCSS decode input of the NHRC. COS from the MII would go to the COS on the NHRC. Rx audio from the MII is raw discriminator, best place is high side of the vol pot (NOT the wiper!) CTCSS tone encode out from the 3200 would go to a CG input on the MII.
