A 4 flat is just stop/turn/running lights, a 5 flat has an extra lead for brakes. If you doing rewiring you may want to go to the standard 7-round that includes a battery charge line and backup light connection. Even though it's only 15' I would think that it would have brakes. Most states require them on trailers over 3000 lbs, but some are less at 1500 lbs or even 1000 lbs. If you are rebuilding this trailer to travel with, you may want to consider adding brakes if it doesn't have them already.
