side marker lights...wiring help

Okay, I just got a wonderful set of 68 side marker lights for my cuda, from another member!


(These pics are from BEA Parts) But my question is why doesn't the rear assemblies come with pigtails and light sockets? My cuda doesn't have them, the wiring is trashed...And if you were to look on BEA's site, the rears don't come with them...So what do I use, if I have nothing to work from?
