Short

Hello everybody. I have a 71 duster that recently had some problems and fried my engine bay harness. I replaced that and the bulkhead connector with new stuff from Evans wiring. When I tried to crank my car smoke came from the plastic connector that goes up to my ignition switch. So I quickly pulled the battery cable off. After I got mad and cooled off I came back and pulled that connector apart and with a fuse inline I hooked my battery back up and it did not blow the fuse. I could tell the purple wire on my alt. was getting pretty hot. Any advice on what I need to do next would be greatly appreciated. And can someone post a link to a factory wiring diagram? Thank you
