Yesterday I was changing oil and working on the water drain valve on the fuel filter and saw this black wire taped back(marked with red line) on the wire harness under the anti lock brake module. I appears to have never been connected and I am wondering what it is for, it is not a very heavy gauge wire. Maybe a 14 or 16. I bought the truck new and put a brake controller in it at the time with the blue pigtail that came with the truck. Snoking
