2003 F150 (7700) Trailer Wiring
Can someone help. I cannot get the correct harness to plug my boat trailer into. I found a connector under the drivers side rear but nothing seems to fit. Someone told me that there is another connector that would give me a 7 & 4 plug outlet. I need advice on where to look for it. Thank you Dennis

Not 100% sure about the F-150 7700 if it follows the F-150 or F-250 wiring.
You can check the Towing and Hauling forum for a sticky on the fuse and relay locations, several have posted the PN for the 4 & 7 pin trailer tow adapter.
What the MY in the thread when you find it, this thread contains both 1997-2003 and 2004-2008 MY part numbers and fuse / relay locations
