I am looking for a pigtail wiring harness for the new 2007 2500 with tow package. I am removing the boxes on them and putting flatbeds that I already own on them. I would like to get the wiring harnesses that plug into them so that i don't have to tap into the wires and when I am ready to move the boxes to another pickup I can. Currently they are set up for Ford pickups. Can anyone tell me where I could find a harness that would fit?
