03 F350 previous owner made a mess of the trailer plug wiring. I'm looking for a new harness that plugs into the trucks harness at the back and goes to the 7 blade plug. Anyone have a part # or source for one? I don't need it to plug into the 7 blade as the factory one is long gone.
I had to replace the whole harness and plug on my 2002 last year. This is the part number I used, 2C3Z-13A576-DA. I wasn’t able to find just the harness section itself.
OK, thanks for the info. $165 for the factory piece, I don't think that's going to happen. $48 or so for aftermarket sounds good. I don't know why they spliced in for a 6 pin up in the bed but they made a mess with scotchloks. Everything I own is 7 pin flat.
Why would you want to do that, that is incompatible with the Standard RV 7-way setups that come OEM on our trucks, and my Suburban also,
it was a rats nest with butt connecters and the like.....corroded wiring, etc. Its just a new standard that makes things plug and play....had to rip out the old stuff anyway. Everything works the way it should.

Thats exactly why I swapped over....i dont need a 6 pin so I just added a 7 pin in the bed. The original was added by using butt connectors and this new system was plug and play.
One thing I did see and I think I found it on this board when I did a search was adding a trailer wiring junction box under the back of the bed. That would work well for splitting the harness to 2 plugs and the bonus for me would be no needing a new harness as they butchered it down near the bumper plug so I could use what it still good.
my whole system was infected.....green and white powder coming from every connection. Rather than try to clean all that up...I just swapped over. It was easy to do......if yours isn't bad, might be more advantageous to keep the stock setup and just replace what you need.
I should have taken pics and made a post, but I did it in 20degree weather so I was trying to hurry. haha The giveaway was that my trailer lights weren't working after converting everything to LED on my dump trailer. I realized then it was the truck....so I looked underneath and got a show that reminded me of my crystal growing experiments in elementary school. Yuck.

Sounds like your truck had been backed too far down a boat ramp at some point in its life.
I wired all of my trailers with a junction box, so much easier. I also use a short piece of PVC pipe zip tied to my trailer jack to place the trailer plug in so it stays clean and dry. Drop a 5 gal bucket over the jack and it all stays in good shape.
