7 Watt CFL Socket -- is there a specific tool to close these copper prongs on wire?
The 2 holes touching, that look like a figure-8, on the side with the writing... are stab connections.  You just stick a right-sized wire in the hole.
The right size is typically 18 AWG solid or tinned.
Hot and neutral don't apply here.  These wires need to come off the fluorescent ballast and must be wired according to the ballast diagram.
