Turn signal switch wiring

Chris Biggs said
Can somebody tell me what the circled item in the picture is and where it's located? Extremely new to auto renovation and need to change out the turn signal and horn.

I'm try to hook up my Painless Wiring Kit to my 67 Dart GT steering column plug. As I look at your picture I understand what wires go where, but WHY is there two for some? Thanks for the help.
