Protank 3 Mini Dual coils

[Ace90]

Hi guys,

Does anyone have a link that can show me how to change Dual coils for my Protank 3. Ive seen tutorials on how to change the Single Coil but I havent found any for Dual Coil. I would like to be able to use cotton instead of the silica wick so I can see what all the hype is about.
-Thanks
