We do not have assembly instructions for the Flowtron FC Fly Zapper components. It is not a difficult task, but it could become problematic if the job is rushed. There are no wiring schematics, so we strongly suggest you take it step by step, wire by wire to avoid any problems. All components are located under the top cover, except for the starters on the FC-7600, which are located on the side cover. For Reference, the Flowtron FC8800 - Has 3 Ballasts, 1 Transformer, and 2 Starters
