I have a 2013 F150 that came with the factory hitch and both the 7 & 4 blade plugs. Today while doing a rear brake job I noticed the plug didn't look right. I pulled on it and the plug from the wiring harness came right out of the back side of the plug socket. I would think that this plug should have some kind of locking tab to keep in in place but something seems to be missing but I'm not sure what? I used some electrical tape and wrapped it around the plug and socket to keep it in place but I'd like to replace the plug.


If someone could post a picture of the plug and how it should look I would like that.

 

You can see the tab, on the harness side, that holds it in place on the socket.

 

I've looked at both ends and I believe that the light grey part on the harness end is missing. And that may be why the plug won't "lock" in place.


I think the only alternative is to get a new plug.
