#4 sparkplug wire on supercharged xterra

Ok, so i have swapped out the #4 plug...problem is now trying to get the new #4 wire on! For the life of me, it seems that no matter what way I twist push or shove the thing will not get in position. I finally got it down into the hole its suppose to be in , but now I cant get it on the actual plug! Any help would be really appreciated!

Mine is a 2002 Supercharged v6

Make sure the end of the wire hasn't been distorted not allowing it to snap over the end of the plug...
