Need help, spark plugs?

1966 Dodge dart Gt with a 1964 225/6

My little nephew was "helping" me change my spark plugs.(he likes to be hands on, he is 6). So I was showinf him and walked away for a brief second and he pulled all the spark plug wires :oops: I'm a novice at best and I have no clue how to set them in order. What's the proper procedure?
