That little hole above is actually to hold in the snap-in wire holder.

Then it goes through the big hole. The wire holder is square and has two tangs to snap over the wire to secure it.

The wire holder in the first pic below is original and has one broken tang so it can't be clipped over.

The other clip locations I show in the second and third pic have been replaced by me with different style screw in holders.

Note: The large factory rubber hood to radiator support seal that mounts at the front of the hood that is right next to the hood indicator. It's very important to cooling a motor. There's a post on FABO where a guy just added a home made foam hood to rad support seal and foam seal around his old warped fan shroud and it took care of his overheating problem.
