While it is easy to do, be aware you deal with 700Volts at high power. You might better get help from a flash repair facility. Internal wiring of the flash head just requires to short the internal trigger capacitor that is placed in series with the trigger coil as broncolor packs already come with an internal trigger capacitor, other than that no modification, just rewiring the plug. BUT be warned: In case you are talking about Grafit A packs, you need to check if the flash tube(s) are compatible with the IGBT cutoff circuit. If they draw to much power you will destroy the output stage which is a very expensive repair. If there is more than one tube or a tube with three electrodes inside this flash box be sure to first check the flash duration when connected to socket 3 of the Grafit pack, as it is not equipped with an IGBT circuit. If the actual flash duration is somewhere in the ballpark of the duration that is shown in the display you should be safe. If it is much shorter don't use it with Grafit A, Move or Scoro packs.
