Based on an earlier post with the Holley Sniper and the ballast resistor wires, when an aftermarket EFI system is added, what is everyone doing with the existing Mopar wiring?

For example, If you were to use the Holley Sniper and the Hyperspark ignition system, what do you do with the old Mopar 5 pin control box wiring. The same can be said about the electric choke wire if you have one. We could take this a step further and talk about one wire alternators as well. Are you tucking the old wires away? Should the harness be cut open and these wires removed as far back as possible?

These EFI systems are sensitive to EMI, would these unused wires be a potential EMI source? Just questions as I ponder EFI while we quarantine.
