I took the positive pin out, shoved a small silicone plug in it to stop leakage, i then pushfit a ss wire into the pos plug, the wire once it enters the
tank is bent to the side to run up along the side of the tank, at the end of the ss pos wire is a crimp that holds the needle post.
the negative i used the compression ground ring clamp thingie from a vision stone innard,it too has a solderless connection crimp clasp for the neg needle post.
without the outer slide on tube u wont have a vape air chamber but could really use anything to rig one up to work, just wouldnt look as good.
the ego version of the phoenix has the outer sleeve tube and even a screw on penstyle cap to cover driptip and it was only like 9 bucks
