I'd like to install a switch to turn my fuel pump off and on. Where's the best place to tap into it?

 

This pic the Circuit Opening Relay that disables the fuel pump in an accident. It’s a located under the dash next to the steering column and has a yellow base.



The B wire (black with a white stripe) is the power supply and the Fp wire (blue with a red stripe) goes to the fuel pump. The switch can go into either of these wires, it doesn’t matter which. Simply cut the wire, extend each cut end to your chosen switch location using the same or thicker gauge wire and terminate them onto the switch. Note that the STA wire is also black with a white stripe, but it’s thinner. Make sure you get the right wire.

 

is this to install a fuel cut switch?

 

Did you read what he asked?

 

Perfect. Thanks.

If your looking for a nice location to install the switch for a clean look this is what I did:

The item is made by Gardner Bender and can be found at most True Value hardware stores, it snaps in just perfect with no movement. The only modification you have to make is to bend the prongs outward in order for the whole unit to drop back into the center console.
