Help, adding a fuel pump cutoff

You can also ground your “tach” wire. Look next to your ignition coil and you will find a white wire with a black terminal, you can run a wire from that terminal to a hidden switch. When the switch it flipped it grounds the coil.

IDK, it looks like the ECM will still get Distributor Reference Pulses and fire the injectors, flooding the engine.

It does lol

In my opinion, it's much safer to put a switch that interrupts the starter as opposed to a switch that can go bad and kill your engine while you're in a construction zone or on a causeway with no shoulder.

I wish I could remember the name of the switch i had in my dodge. It was a gray computer chip thing that you had to plug in in order to start the truck.

Couple of spade connectors and an inline fuse,. remove the ecu/ecm fuse (#11??) use a latching push button
Theives will likely tow the truck if the really want it,. or if its in a quiet location they'll break the column pin lock and bust the key tumbler out,. if it doesn't start they'll run the battery down and give up. jmho from experience.
