Each box contains similar components, so lets focus on the Blue CCFL box for now. The contents of the box are listed on one of the sheets of paper which also has a picture with labeled parts so that you can clearly verify that you received everything.
Included is a 12 inch CCFL (Cold Cathode Flourescent Lamp), pre-installed acrylic tube with cube ends, Velcro pieces to mount the CCFL, Dual Inverter, Inverter cover (Velcro wrapping), Wire harness, Extension cable for the toggle switch, and a Round toggle switch with washer. What is not mentioned is that Sunbeam adds female disconnects to the switch wires so that you just plug the switch in, there is no need for solder or other methods to attach the wires.
The wiring harness has a Y-splitter built in so you don't lose a power connector in the case when you plug in the dual inverter. The Y-splitter part is about 11 inches long. The inverter connects to the first molex connector so the other molex basically acts like an extension which should be handy in larger cases. The wires from the molex to the inverter is 18 inches long and in the middle there is the connection point for the switch. In case you need the additional room, Sunbeam has included a 10 inch extension cable that uses molex quick connects so there is no need for wiring.
