Anyone tried one of these HEI Distributors?

Got my distributor today. The cap is male hei style just like the picture. Not sure what the guy on the phone was smoking when he told me it was female mopar style. Can't try it yet because now I need to get some spark plug wires ordered.

The box is white with absolutely no markings. The distributor has no part numbers of any kind. Worst of all, there's no instructions.

I called to ask them how to hook it up. They said to wire it to the coil, black wire on the negative side of the coil and red wire on the positive side of the coil. The odd thing is that the red wire has a spade connector with a white plastic shield around it. If I'm supposed to hook it to the coil, then why wouldn't it have the round lug like the black wire has?

If anyone has installed one of these successfully, let me know how you wired it.
