07 Caliber starter relay wire connectors

[327chevy]

Mother in law has this Caliber and recently had to replace the battery because it wouldn't hold a charge very long. Went to start it today and nothing. Looked online and the most common issue is the relay for the starter. Got access to that but the problem is the red wire rotted off the connector. If possible I'd like to put another oem style connector back on so it fits the mounting block. Wheres the best place to get connectors? I'm sure any Dodge dealer has them but is there an aftermarket one that fits? If I can't get one tomorrow I'll likely end up making a pigtail up and routing the relay out of the way and elements as best I can.
