Pigtail not fitting....

We just purchased a new tow vehicle (same make/model as our former TV, just younger) and the trailer's pigtail won't seat firmly into the socket on the truck. It's a 'blade' set of pins and the amount of pins and location of them are all matching and the pigtail goes in just fine but no amount of jiggling or pushing makes it go all the way in. We've tried a little WD-40 and that didn't make any difference. The plug cover (which is hinged to pull upon in a downward fashion) has a plug 'stop' that braces up against the pigtail in the right place but doesn't hold it securely at all. A few jiggles down the road and I'm sure this thing will disconnect. A search yields up that many people have the same issue and just use small bungee cords to secure the pigtail to the plug-cover where the 'stop' is. Not sure that this is the best answer. Do we need to replace the pigtail so that we get a secure/full seat on it when plugged into the new truck or is this as good as it's going to get?
  • Search images on the web to find the correct plugs. It sounds like these are not a match.

    Once you find the correct match, go spend $10-15 for the correct plug and wire it up. You can find the wiring diagrams online and it's pretty simple.

    A bungy cord and a prayer are not a good solution.
  • New vehicle? I would consider taking it back to the dealer and see what they think.
  • First do not use WD40!
    Not all connectors are interchangeable. The protective cover on many hold the connector in place.
    Make and model of truck?
    Some new rigs use somewhat of an adapter connecting the truck wiring to trailer connector. If equipped, insure the adapter is seated and the retainers are in place.
  • Fix it once..right. New pig tail IMO. I did that when I purchased new truck. Slides in easily and is secure.
