yes Bob u got it , the grey wire we isolated is the wire that supply the
signal from the tach to open and also the grey wire tells the micro
procsser in the black box that we have already cycled the system once , by
disconnecting the grey wire we are now just using the yamaha box as a relay,
for people who are not running a stage 7 like us and want to retain the auto
Vboost u can go one step futher and use a toggle switch with four posts on
it and tie in the grey wire to it , then u have everything , i just wanted a
easy way to open and close the boost with limited number of wire running to
the toggle, i am taking mine one stept futher, i picked up a micro lite at
radio shack also that iam wiring in that will lite green when the boost is in
the full open pos. (not really needed , but will look cool)lol. also by
using the yamaha box u can keep power to it at all times if u want and it
will not burn up the servo, the proscesser in the box shuts off the power
automaticly even if you leave the toggle in the on pos.
