Good morning all. I decided to install lighting myself. I bought an Icecap ballast kit but have a few questions. One, the ballast will be mounted on the outside but do I need to install a fan for the ballast or inside for the lights. There will be two T-12 bulbs. Also, the power cord has just bare wires on the end and I can't figure out how or where they go into the Ballast. Any help would be appreciated. Thanks
