I wouldnt ream it out personally!!!!! Unless it was like 1000th of an inch!!!!!

To be safe I would use a smaller guage wire, leave 1/4 to 1/2 of an inch of slack coming from the eyelits. Strip the wire and solder you 14g to the wire coming from the eyelits.

You could also heat shrink the solder job to make it look more apealing.
