What's the best way to wire a fuel pump security shut off toggle?

[ModestMussorgsky]

I've got no money and alarms dont work anyway, so I'd like to run a secret toggle switch that shuts the fuel pump on/off.  I've seen a few guys wire back from the fuel pump relay through the firewall but that seems like way too much of a task.  I'd rather work in the dash if possible.  Anyone know how to do this?

You won't be able to control the FP inside the truck as the PCM controls it and that is under the hood. Maybe put the toggle on the power feed to the ignition switch

If you don't want to go between the fuel pump and ECM or fuse box in the engine bay, you'll have to look for something that the Body Control Module, BCM, under the dash controls.

 

You'll of course need access to the wiring diagrams for your truck.  For a few bucks you can get a temporary subscription to them at AllDataDIY and other places as well.

Good auto insurance is the lazy persons answer.

I've been thinking about something like this also.  For simplicity, maybe just put the swith in the pump ground wire, (if there is one).  Cut the ground wire, extend it to some hidden location in the cab, put the switch where you want it (hidden).  No ground =  no circuit = no run.  ???
