Yeah that's for sure. I have an 85 D150 w/a slant 6 that I'm surprised lasted all these years and was even there for me to have a chance to buy..... I'm really surprised this thing didnt end up a fireball years ago. bad enough I didn't even try to fix the original harness. I wound up finding another truck in the junkyard with a harness in MUCH better shape, and went thru that one to verify all was good with it, only found a couple nicks in the replacement harness from age, heat, and having "taken a set" in place, and a couple of "oop's" from the process of transplanting from junkyard to my truck....
