turn signal wiring harness
 

I just bought a new turn signal switch and connector for my 68 mustang. When I went to replace it i notice the connector only has 10 holes but there are 12 wires.The original harness was the same. Now I know ford will not add 2 wires fro no reason at all. so could someone tell me what I am to do with the black and yellow stripe wire and the brown wire
