operate fire extinguishers. The circuit breaker triggering
system on saloons should be located at the lower part
of the windscreen mounting, preferably on the Driver’s
side or below the rear window. On Open Cars it should
be located on the lower main hoop of the Roll-over Bar
on the Driver’s side, or at the lower part of the
windscreen mounting (as above).
76.On cars of periods A to F, the mounting point may
also be mounted approximately vertically below the line
of the scuttle on the Driver’s side. The location must be
identified by a red spark on a white-edged blue triangle
(12cm base), and the ‘On’ and ‘Off’ positions clearly
marked.
Then why is there an electrical cut off marking next to the extinguisher one on the porsche? Also, in the image below, hard to see I know, but see the black cable that disappears behind the handbrake? It's the other end of the T pull cord that's mounted outside the car.Quote:

This picture below, a friend of mines 2008 S1600 campaign car. Note pass side of bonnet toward scuttle panel, thay little blue sqaure. Under there is a waterproof switch for isolation, next to that but out of view to the left is a mech T pull for extinguishers)

Incorrect mate, one for in car mounting (driver/codriver trigger) one for external mounting. Note x2 brass mounting nipples on the handle of the red extinguisher ;)Quote:
