Need HELP in BAD WAY!

I am restoring a 74 Duster. I just got the engine running after some issues and during my initial breakin run about 10 minutes after start up, my engine wire harness started to burn down. I had all of the harnesses out during paint and do not know what went wrong, but the fuse link on the red wire from the battrey to the amp meter melted into the bulkhead connector, destroying it an I have some othe issues around the connector behind the right valve cover by the blower motor. It looks like something went wrong there because a wire was melted in the blower ground wire and that is what caused the problem, AT ANY RATE. I need a replacement engine wire harness for a 74 Duster with a 318. CAN ANYONE HELP PLEASE?
