You do need it, its a collision switch that cuts power to the fuel pump in the event of a prang. If you dont have an original there are plenty of modern ones available that do the trick fine. Land rover ones are a favourite. like this Cutoff switch when you order it ask for a bit of the loom with the plug for it to make life easier. Stuart.

john.r.davies Posted February 23, 2022 Report Share Posted February 23, 2022 if rick's car is running with those disconnected, then someone has hotwired the fuel pump! Quote Link to post Share on other sites

I think ii have a spare original one somewhere if you’d like it? If you go for the jew Rover one, as many including myself have, make sure it is wired to actually cut the fuel in the event of an impact, as they can be wired incorrectly. steve Quote Link to post Share on other sites

PodOne Posted February 23, 2022 Report Share Posted February 23, 2022 Apologies for highjacking the thread but my 1969 PI didn't come with one fitted and the harness doesn't have the wires. Was the cut off a later addition for the American market or for here as well. It seems like a sensible safety feature to consider incorporating into my build but if it was never a feature of the car is there anywhere else other than the bulkhead where it could be fitted to maintain originality? Wiring wise I guess the switch sits between the white 12v feed to the pump. Thanks Andy Quote Link to post Share on other sites
