[HAM] Switch for relay coil on Leslie 25 ?

[David Damroze]

  My connector for the Leslie has the switch for console/auxiliary 
(echo) but not the tremolo switch.
  As near as I can figure out , somewhat adapted the 27-1 console 
connector without the 26-1 i.e.
  they used a 5 pin to 6 pin cable to connect the speaker with the 
result that I can switch between
  the organ speaker and leslie  but cannot actually activate the brake 
on the rotor.
  The Leslie is either full on with tremolo , or disconnected from the 
signal path all together .
  I'm wondering if there is some way to wire a toggle switch with a 
cable directly to the relay
coil on the Leslie.  What kind of voltage is in that circuit ?
  It looks to me like wiring a switch across pins 2 and 3 would work , 
but I'm a novice at this.
