The first problem that I had was that its terminals are not clearly labelled. I needed to pick off the hot and neutral from the four terminals in the back, which were labeled A-D but that's it. No schematic on it, and also Corcom's documentation is completely demure, showing some schematics with no hints as to what the terminals on the schematic are (in some schematics they are labelled 1-4 which is suggestive of an ordering like A-D but not definitive.
My application was 120V, just the hot and neutral. I finally found that Corcom sells a connector for the unit, part number PA105. Finally, I found a photo of it off of the DigiKey catalog that showed it. The white wire is on one side, the black on the other, based on the keying tab I could tell which went to terminal A and which went to terminal D.
Here's the DigiKey page for the connector:http://www.digikey.com/product-detail/en/PA105/PA105-ND/1288422

The Mouser catalog was no help:
