I am just writing this to help someone if they have a similar situation as I had. I have a 2003 F250 and some how the previous owner messed up the harness that plugs from the rear under the bed to the 7 way plug and I was getting shortouts and blown fuses. So I go to every parts store ( Napa, Autozone, Advanced etc. etc.) to find a replacement and nothing was available. HMMM? So I go online and find numerous ones for an 99-01 but not an 03+. So I called Ford and they quote me $180 for an 18" harness with 7 wires and 2 plastic ends:doh: So what I ended up doing was order one from etrailer.com for an 01 and spliced my good end onto it and its working again and I did it all for $75. I should have taken pics to help everyone but didn't think about it.
