making a switch

hi people. i have a question. Go easy on me.
I want to make a kill switch of some sort for my car.

What im proposing is to put a switch to disable my fuel pump power.

How would i go about this? I have absolutely no clue. im a n00b.

They're are normaly fitted into the boot (trunk) of the car and are activated by a trembler switch should the vehicle stop suddenly as in a crash.

If you wish to operate it from the drivers seat you will need to fit a selenoid operated valve in the fuel line and a toggle switch in the car. Disconnect the battery during the fitting to prevent sparks.

Cut + line and connect the two ends to each switch tag this will break the current supply to the pump.

thank you very much for your help

I assume that you plan to hide that switch ... makes sense to. There's a slim chance that depending upon your vehicle's computer controller, an error code could be set if you try to start the car with the switch off resulting in the SERVICE ENGINE light illuminating or whatever device is used to alert you. To extinguish that lamp, you'd either have to disconnect the + battery terminal for several minutes or use an OBDII scanner to reset it.
