HEMI MDS questions

I would think you could operate the solenoids easily enough with a toggle switch, but shutting off everything else associated with the system might be hard. You'd have to cut the fuel injectors too if you're not running a carb at the least as well as the coils. Not sure what else is tied into the system. I have read there are a ton of parameters associated with turning it on and off in the computer, but not sure how many of them really matter (oil pressure, oil temp, rpm, wheel speed, etc.).
