OK, here's the deal on that ignition switch. Like most aftermarket parts, it's made to fit more than one application. E-bodies use the pre-crimped ends that are on the switch. 75-76 Valiant, Duster, Dart and Dart Sport use a separate connector that is included with the switch. You have to cut those two wires and crimp on two female spade terminals for that application.
I wish it would have just come with two sets of loose terminals. That way I could have cut the wires to the proper length before inserting them into the connector. There is also an extra ground wire on the new switch that wasn't on the original switch. Some applications had an extra ground...some didn't.
