R26 battery cutoff switch

The autolec battery cutoff switch has an auxiliary contact (5A rated) to cut the ignition circuit when the switch is operated thus killing the engine immediately. Has anyone a suggestion as to where to break into the wiring to achieve this (somewhere nice and easy). Does anyone have access to a decent R26 engine bay / fusebox wiring diagram ?
 
For everyday used, i fitted a cutoff switch, by interrupting the negative terminal, and at the same time, moved battery to boot.
