7-Way Plug Intermittent
Anyone have a problem on occasion the 2012 Flying Cloud break lights or turn signal lights may not work. When I "jiggle" the 7-way plug in the 2012 Tundra socket, brake lights and/or turn signals work again. I have cleaned the plug and socket with a Q-tip and isopropyl alcohol. Any suggestions?

Either the socket or plug has an issue.
Could be loose wires inside the socket or plug. Repair as necessary.
Could be corrosion. Clean the contacting parts with abrasive then coat lightly with dielectric grease.
Could be debris/foreign object. Check inside the slots and inside the plug
Could be wear or defect. Replace worn or defective parts.
Some people use a zip tie to connect the socket and plug more firmly. This also reduces the possibility of the plug coming loose while towing.

The contacts on most plug ends can be bent inwards with a screw driver to close the gap between them.

I trimmed an emery board to fit in between the female contact cavities and burnished the contacts---and male contacts. Cleaned with compressed air. Dipped a ladies cosmetic brush ($2) in isopropyl alcohol and scrubbed all contacts. Dried with compressed air. All connections are working find on our last Airstream move. I am also planning to wrap my molded cable connection / contacts with a desiccant, especially in wet / high humidity areas. I think the problem was corrosion!

Your Tundra, is the 7 way plug cover hinged at the top or bottom?
Bottom hinge might really need a minnie bungee to help stay connected after your cleanup work on connections.
Mine is top hinged and i use one too.

Are you sure it is plugged in all the way? Took me longer than it should have to find out I have to hit my 7 way a good live with a hammer to get it to engage the last 1/4 inch or so into the socket. Once I started doing that and getting it plugged in all the way all the little mysteries and disconnects went away.

1. Put some electricians grease on the connectors on both the truck and cord and plug back in. You should actually do that once a year.
2. It could also be that while your traveling the connection is not secure. Might try something that would keep your plug securely connected. Not sure what that might be since it depends upon your truck. But a suggestion is to use duct tape and wrap it to secure it.
3. It could be there is a short in some wire in the plug connection. In that case you can take the 7 way connector apart and examine the wire connections and or clean as necessary.
4. It could also be that there is a wire that is shorting in the cord itself. In that case you would need a new cord and connector which you can get on Amazon.

My 2012 Tundra 7-way plug is side hinged and it shuts ok on the molded cable receptacle. You can do slight adjustments on the hinge but since I roomed corrosive film, brake lights and signals are working fine as I tested them at intervals on our last 145 mile trip, which included a very bumpy 3 mile camp site road. I plan to wrap the molded connection in dessicant to slow down corrosion.

Yes, a rubber mallet (hammer) is good for all things, see my other posts how I removed corrosion.

See my other posts how I fixed connection with good old cleaning. Dielectric grease may attract debris that needs cleaning so I am not embracing that. Thanks, good idea.
