"Wired" tonight!

I was in the process of installing the aluminum valve covers and realized halfway through I had no Ultra Black so I figured I'd throw on the new wires right? Well I got some strange wires or it's a Mopar thing? Check it out these are MSD Part # 31319. Whats with the different boots?

Thanks in advance,

Im calling MSD on Monday Im sure it's packaged wrong.
