For those that where not present in live chat, when I described how to do the gunsmoke.
Basically a gen N Juice combo was an idea so people would not have use a juice compartment that uses a needle injection method.
So you just have to seperate the battery compartment (instead of using a straight line design).
Now wire the first wire down the side of the top and into the screw on compartment.
(Use a sealant around the top screw cover.That is where the wire goes in you can also seal around the rest of the scre cap if you want a good seal, that is once you have measured your desired length. I find if you solder a piece of metal to the end of the wire you can make a clip this made things easier to test, at least it did until everything got took apart.
second wire goes outside the juice compartment so thats pretty much it.
You can make a straight pipe ------ the regular way or you can use a parallel pipe design ---____
Enjoy modding!!!
