but isn't your pump then always live, no matter what?
Elec. pumps should really be wired, so they only operate when you turn the ignition key to 'on'
Apologies let me elaborate.
Two ways of hooking it up.
1) straight from battery with an inline fuse and switch (yes I did forget to add that)
2) corrected via relay power coming from battery signal coming from ignition barrel.
In all the cars I've fitted it I've used option one mostly. It also serves as a theft deterrent if the switch is well hidden. My gtv had it under the steering wheel
