Your wording is confusing.........
What is the "last thing" before the power gets to the MSD "small red?
Same question the fuel pump relay.
I don't know how you have things wired........original Mopar ignition switch is not fused.
But essentially You have battery.........maybe a fuse, maybe not.........ignition switch.......back to disconnect.........back up front.........to MSD and to pump relay
