For typical straightahead wiring, they do not connect to anything except each other. Solder the red and white wires together, then wrap some tape around the connection or use heat shrink insulation if you have it.
Now for a coil split push/pull switch, this red/white conection would also be soldered to one of your spliter switch lugs. See this diagram... http://www.seymourduncan.com/website/suppo...matics/hr2.html
They are using a mini-toggle switch, but with a push/pull pot it is the same.
This feature gives you the ability to switch from the hot humbucking tone to a thin, bright single coil sound with the flick of a switch.
Personally I prefer as few switches as possible...plug in and go. But that is just me.
