Does it have separate coil packs?
Yes, switch it and see if code shows a different cylinder,if it does replace it.

The cylinder 6 mis fire went off when I re did the wires I think is was a bad wire
correct,replace the coil. don't be surprised if it's more than one that failed.
Sorry I see your misfire changed,you said you moved a wire? I thought you had separate coil packs?
