On my 2006 F-150 there is a 7 Pole RV connector next to the standard 4 Blade connector.

How do I find the wiring diagram for the 7 Pole connector? I looked in the owner's manual with no luck. Also, can I use any "standard" 7 pole connector? Or does it have to be Ford only?

Help is appreciated.

 

I believe the diagram is on the cap, if it's like the Super Duties. Will fit the standard 7 pins. Take a look over on the towing forum too, lot's of great stuff there....Brian

 

I looked at the cap. I see a wiring diagram on that, but when I compared to the coupler manufacturer, they show two different wiring diagrams.

Also, the F150 female housing on the truck has ridges which align the male coupler. None of the couplers I've seen have ridges.

Needless to say, I'm getting more confuzzled by the moment.

Thanks for the links!

 

The 2 different wiring diagrams you are talking about might be because of the "view" direction of the plug diagram, ie...the truck plug...looking at the plug from the rear of the vehicle(where the trailer connects) the left turn/brake will be on the left versus if you view the plug from the front of the truck(where the actual wires connect) the left turn/brake will be on the right...a mirror image and the same thing.

Also, I think I read somewhere that some or all horse trailers are wired a little different. If I remember correctly they may switch the 12v and Aux locations, but not sure, never owned or worked on one. Aux is usually for backup lights.

Another thing, you can wire the plugs any way you want(not industry standard) as long as both are wired in the same order(I only recommend this if you only pull w/ the same truck/trailer combo). I believe it was "Mil1ion" the posting legend who did this so if someone stole his trailer, the lights wouldn't work right and more possible to get pulled over by law enforcement. Or if you have electric brakes on the trailer, switch the 12v and brake wires on both of yours, and if someone steals the trailer, the trailer brakes will lock-up. This of course, is only if they have the standard 7-way wiring and leave the plug connected, a long shot, but you never know. I have construction friends who do this 'cause construction trailer theft around here is pretty high and anything is worth trying.

As to having to use a "Ford" plug. Once again, the industry standard is one square ridge on top. Any aftermarket plug that fits will work. And you probably have the 7-way "spade-pin" type plug. There are also 7-way "round-pin" plugs out there, not as common though, but you cannot mix them. The "spade" and the "round" refers to the shape of each of the 7 pins and not the shape of the whole plug. Hope this helps and good luck, Dave.

 

Thanks again Phil.

I'm going to post a pic of truck connector as soon as I get done with my weekend work rotation.
