I did only the one mod which was .
9.6v to a 10k resistor to the base, emitter went to ground, collector

That part of the modification is not intended to drive a controller - it
is intended to drive internal cards after doing the modifications
suggested for better muting.
You simply need a logic inverter:

Disregard the (mobile only) note - this circuit is what you need to
drive a controller - whether or not you have a Mobile or Station.
