I repair cars as a hobby for a nonprofit that donated them to the poor. Many of the cars they get donated to them have suffered engine fires and the hardest part of turning them into a decent everyday driver is finding a replacement wiring harness at a salvage yard. As a rule, salvage yard workers just cut wires when they pull parts, so finding an intact harness is like finding that proverbial needle in a haystack. Buying brand new harnesses from the manufacturer is just too costly for the nonprofit, so I make my own wiring harnesses. I love these connectors because I can solder the pigtails to my harness, insulating the splice with heat shrink tubing. With 16 pigtails to work with, I usually have a few left over for future use if needed. These pigtailed connectors will work for rewiring any vehicle—car, truck, bus, boat, trailer, you name it.
