Search your local hardware store for something like this. Then you don't have to worry about cutting the end off.
You should buy some heat shrink tubing also to fit over the leads.
When I looked in my local store, I didn't find any receptacle. But its supposed to "snap in" To what, I don't know. Sometimes, they don't even come with fuses. Let alone mounts.
Someone posted a nice picture of the one they did. Hopefully someone will post it again.
