NO and a Warning: That is where the main gun barrel Flash Unit plugs into the DMD Unit.

Flash Unit for the Barrel = CN7 M.G. Fire

Hull Machine Gun = CN3 G. Fire

Do not mess around and do free style plug and play solutions and try other plugs at random to trouble shoot issues! You will no doubt fry everything if you do that!

You must follow the Tamiya directions exactly.

This is not a creative out of the box exercise, your now in Japanese engineering assembly land with this Pershing build. LOL.

Read your instructions at least 5 times before you touch anything. You must read and then do. There is no way around that fact.
