Wiring a fuel cutoff switch
I am currently converting my XF to EFI. As I am wiring up an electric fuel pump, I thought it would be a good idea to include a fuel cutoff switch for security.
I am going to have a microswitch in the cabin and use a relay.
As far as I know the wiring for the relay will be;
30 = Power from fuel pump relay
85 = Earth
86 = Power from switch
87 = Power to fuel pump
Is this correct?.
Where does the Earth wire from the switch go?.
