Help ASAP Please? Spark Plug Wire Exchange?
 

So, long story short, after I had changed the plugs and coils, the husband thought he would do me a favor and take all the wires out without putting the new ones on one at a time, so now I have no idea which wire goes to which plug and which coil? Is they a DIY that I am missing? Or does it even matter?

This pic easily shows where each wire goes:
