Most modern fuel injection systems supply power full time to the injectors. The ECU will supply a ground when it wants the injector to open, and then disconnect the ground to close it. There is usually a single source for the power to the injectors, which then gets split into individual power leads for the injectors. Find that single source, and you can kill all of the injectors by interrupting one wire.

Some cars use resistors to drop the voltage going to the injectors; usually the single wire goes in to that box and is split in there.

That's where I'm planning to hook in my kill swtich on doing to my CRX.
