Keeping it Mopar Ignition Upgrade Cheap

If your Mopar system is properly working, you won't see much difference, if any.

The relay is an alternative to actually getting the wiring "back to" full specs, as the wiring path from the battery......through the bulkhead, ammeter, switch, connectors, and back out the bulkhead is often less than "up to snuff."

This same switched ignition supply also supplies your regulator (and a couple other things on some cars) and can cause OVER charging.
