In search of correct wiring harness

Hi everyone. Sending huge hugs and smiles to you all.. looking for some direction to go towards..I have a 73 dart swinger 318 engine stripped down completely. Just got my block back from the shop. I trashed my stock wiring harness due to melted wires...melted connectors...wires just hanging...tape here.. tape there.. I'm about to order a harness but I'm not sure which I need ( came across so many) . If possible I'd like some suggestions from all you knowledgeable Mopar Geeks in here. As of now I have ZERO WIRES to be found in the swinger. Do I need to buy a harness for the bay and one for the cab or is there a complete set for motor and cab accessories? If the question gets asked...Everything going back in will be after market hi performance parts.. Thanx in advance my peeps.. Much love
