Trying to help nepthew with his car, got the ingition switch connector,turn signal switch connector connected to harness,but there is another connector(flat 3 term. violet,tan green wires-comes from turn sinal switch)but i do not see where it goes? or what it may be connected to?

My 73 Dart has a third connector for the lights in the gear indicator and for the lighted key that's on a delay. Forget what the 3rd is.

Thanks for reply,his column does have the lighted key,but that wire was a single yellow wire with connector,and that was already connected to the time delay
