I have a smaller omni flash version for a Gauntlet. What you are missing is part of the safety cage that attaches to the print head after you flip the head up. Once you install the cage, the temp controoler box hooks on the cage. Thr ir panel attaches to the print head and hangs off it. The cage does 2 things, holds the controll box and keeps people awayfrom the heat panel when it is at rest. You will still be able to install and use the flash, but not the safety cage. Many people will put the temp controll panel on a chair, wall... The cage can be a pia if you need to move the flash on a regular basis. Newer, similar ir flashes do not come with cages, all the heat controls are self conatin with the panel. The falsh in the picture might be a different set than the Gauntlet Omni flash.
