Security : fuel cut off switch?

[Tcamper1963]

Hi,

I am thinking of having a hidden fuel cut of switch in my ford transit mk7 so that it acts as an immobiliser.

1. Has anyone had one of these fitted?

2. Do you think it's a good idea instead of or as well as an electronic immobiliser?

Thanks in Advance...

My 1999 Ducato. Found positive supply to fuel pump. Cut it, looped a wire to dash and back. Also known as a kill switch.
