Exactly the way the rebuildable is on vertical but both wires go out the bottom. One wire folded over and install rubber grommet and one wire through the middle and install pin. Same as every coil. On Utube check out vertical Atlantis coil rebuild as most coils are done exactly the same Just different coil size and ohms.
I posted a test in another thread, I coiled and wicked the Tron-S and Cubis exactly the same and the Tron-S blew the Cubis right out of the water for flavor. Wife did not believe me it was the very same juice. CHEERS!
