Well i dont have any connectors in the airpath . I twist the cables on the end where the bulb attaches. My wires are 316L. I use connector only at the plug,outside of the airpath and in the latest model outside of the vape. Once you have materials at hand i am quite sure you will be able to work yourway around this. Thinking is much more productive when there are real things infront you,instead of schemes and diagrams,but that is just me.
