Did you try looking at LMC, Bronco Graveyard or Dennis Carpenter web sites yet to see if they might have what you need? If you have more then one wire feeding off the battery, you might have to replace just the positive cable, then put terminal rings on the other wires and attach them individually to the terminal bolt. I understand your dilema but sometimes you have to find a cheaper out that still does the job. Otherwise, you might have to hit up your local junkyard for a good replacement wiring harness.
