Its an eletric trigger from the ecu at a set RPM (4200 I think?) which opens a vacume valve to the large black vacume resivior (under the intake) which links to the actuator to keep the TVIS butterflies open

Yeah, electric vacuum switch, but the butterflys are springloaded open, the vacuum is used to close them below 4200.
Hey dad, getting a bit muddled in your old age eh?
