7 Way Trailer Plug In Bed

Trying to put a 7 way plug in the bed of my new 2015. My truck does not have the 5th prep package. It only has the 7-way 4 way combo by the bumper receiver hitch.



I found a 2013 F350 in a junk yard with the 5th prep package that has the 7 way in the driver side of the bed. I have not looked closely at it yet though. So I dont know how it wires up.



I'm thinking about grabbing it, but not sure if or where it will plug and play into my truck.

I do not want to cut and tap and splice to make it work. I want plug and play.

I found these plugs under my truck. Driver side by spare tire. Is this where it may plug into?



If this factory part wont plug and play, I'm thinking it may be easier to grab ones of these aftermarket ones that do claim to be plug and play...

Pollak 7way

The aftermarket plug and play are extremely easy to install and best of all, you will sure all is working when you are done. That is what I use in my truck. You are wise not to waste your time and mess up your wiring attempting some of the splices I have seen.

I used the aftermarket one. Worked great and was easy to install. Just make sure you have enough room to plug it in. I mounted my plug up high in the bed and had to use a 3/4" piece of poly to make a spacer.

The Ford add on is the way to go. There are some who have had connection problems when trying to maintain a good connection with the feed thru 7 pin connector used in the after market setup..

After looking at the dual plug setup on my truck - one had two pins, the other had 5 - I went back to the junkyard to look at that donor truck.

It had the same plugs by the spare tire. I unplugged them, followed the wires which led to the 7way mounted inside the bed.

Removed 2 10mm bolts and $20 later was the proud owner of a junkyard 7way connector and harness.

Got home, plugged into my plugs, tested... everything worked as it should.

Drilled a 2" hole in the side of the inner bed, fed everything thru, routed wires neatly, plugged up mounted up and tested working as it should.

Not bad for a morning's work.

Thanks for posting. I am thinking about going the same route with my truck if I have those plugs back near the spare. The pictures are especially helpful.

great.....i think you will like it better than the setup that plugs into the existing 7 pin plug by the bumper...

That plug is mounted a bit higher up from the factory...maybe 5 inches higher and 2-3 inches further forward towards front of the bed...

The one at the junk yard will work just fine. The wiring is the same on all trucks for trailer wires. All the colors are standard. It mounts up high so as to not interfere with the bottom of the bed. if I could find a junk yard with one of those I would love to have it. I got a aftermarket harness and need to make a stand out box so I can mount it under the bed rail out of the way. +

When I moved my plug to the bed I also changed it to the round pin plugs.

I bought an aftermarket one (Curt) from Amazon and it couldn't be easier. I can't see any reason why the 7-pin connector at the rear won't work just as well as the factory Ford one.

Also, I mounted the receptacle up high near the front of the bed, since I use it for a slide-in camper, not a fifth wheel.

Nice job Ginther

I mounted mine in almost exactly the same spot n my 2006 which works perfectly, that factory pic u posted looks way too high to me (no room for Wire Loom) but what the hell do I know...lol

BTW, I had just bought the A/M version (very easy) FWIW

I got rid of the Hopkins in bed I had put in and went with the factory in bed 7-way just as picture above. I never liked having to tie-wrap the connectors on the Hopkins together and the 7-way always seemed loose.

The Ford harness is the way to go, less extra wires to tie up, solid connections on both ends. Wish i had done this the first time.

Wink Factory Mounting. . .

Here is where they mount it on the Factory setup. High up with an offset bracket to allow room for the plug between the outer and inner truck bed walls.
