550L Dominator - where to fit a Safety Power Switch module?

[PHewson]

I am trying to find a suitable location to put my Emcotec Safety Power Switch on this heli.
Has anyone fitted one?
I have found no pictures as of yet.

I have the VBar current sensor, plus the optipower backup guard which is at the back of where the battery sits, on the base plate.
ESC sits in the nose on RHS
I think the wiring should be Battery => Safety switch => Vbar Current sensor => ESC

Any suggestions would be appreciated.

Regards,

Paul
