Then I installed the LED for the transmitter of the Battle Unit AND THE Flash Unit INSIDE the 105mm Howitzer barrel (pcd1964's clever idea as he did on his SHerman) and then zip tied it to the elevation arm as normal to keep it from tangling on the gear..then using double sided tape neatly attached the flash unit to the rear of the turret...
After this I followed the instructions to attach the lower turret assembly to the upper turret and neatly organize and exit the bundles of wiring out the center of the turret..
