Ignition Connector - source and wiring

1968 plymouth Barracuda 318 torqueflite - ignition on dash

#1 I am trying to source the wiring connector pigtail connector that plugs into the ignition switch
if i cannot source it for a reasonable price i could re do it with shrink tube and all. but looking to see whats out there.

#2 I am looking to see if i could find that ignition diagram for this i tried google but no luck looking to see if someone has it also might be helpful to pull from here for future issues.

i was replacing my ignition switch with a new one and noticed my ground wire was no where to be found - this cant be normal.

wouldn't this cause an issue? what kind of issues?
car was running fine and only very rarely ever got a no crank situation.

Diagrams are easy and free, I've posted this a jillion times on here. Go to MyMopar there are FACTORY service manuals as well as aftermarket diagrams

The ground is not used.

AH! OKAY.... really?

in that case ill just fix up the wiring on the cracks exposing the wiring
