Sorry at work and don't have any pics essentially it's this:
Normally you would screw your topper into the 510 connection, which has it's own connection to the battery. Multiple points equals a greater chance for resistance and voltage drop.
The Origin's top unscrews, exposing the top of the tube and the battery. On the Aqua there is a bottom cap that houses the 510 connector that you unscrew. This leaves
threads exposed that will now screw down on to the battery tube of the Origin. Because you've taken away the 510 connection on the Aqua you need a flat screw to screw back into the base of the Aqua which will now touch the top of the battery directly.
Make
sense?
The reasult is a smooth tube with no break from the switch to the airholes on the Aqua. Look at the Origin and imagine the top shiny ring with holes around it missing and the Aqua stuck in its place.
