Put the female receptacle on the power (supply) side so the exposed male pin is not live when disconnected. For multi-wire plugs, see quick disconnects.

FAQ

Are bullet connectors waterproof?

Only the heat shrink versions, which seal when heated.

Do .157" and .180" fit each other?

No. Use a male and female of the same size.
