7 Pin Round to 7 Blade Trailer Connector Adapter Needed
I am new to the forum and new to Airstream. Just bought a 1970 Caravanner. Is there a thread or can someone give me advice on where I can buy the cable and connectors for the trailer lights? The Airstream has a 7 pin round and my towing vehicle has a 7 blade. Thanks.

You'll need to get an adaptor from your tow rig to your trailer. I would try an RV store, they may have to order one.

The flat blade connectors often fail, as one grain of sand will stop a proper connection.
The round terminal connectors don't have that problem, since the terminals are self cleaning.

Disconnect the house battery common/ground terminal before removing the trailer end plug. Especially if it is made of metal.

I have used my GM flat blade connector for 10 years without a problem. The flat blades are also self cleaning as you push the plug into the connector. Sand is easily dislodged. By not changing to the round pin, your tow vehicle will remain compatible to many other trailers that follow the industry standard.

I haven't had any troubles with the flat blade connectors and I have them on several units. Even to connect the solar panel to my trailer.

7 pin round to flat HELP
Hello good folks
Same issue as Jeremy ... if I purchase a 7pin flat to 7 pin round does the wiring set up transfer to the TVs wiring output setup as per the attached photo ... hope that makes sense ... essentially what I see on the forums for wiring on round plugs (female round Trailer) do not match what I see on my TV outlet (male rectangle TV)
Please advise if you know
Best
Rob

I changed the plastic flat blade connectors for metal round pin connectors - socket and plug. The connection pattern is different, though. I think the quality and connectivity are better, although it means that hooking up to a different trailer would be a problem.

Hi rob. I bought a cord from out-of-doors mart that had 7 pin round on one end and 7 blade flat on the other and it worked great! All lights and signals operated fine. Difficult to find and not cheap, you won't find them on amazon or oreillys unless you plan to use your 4 pin connector, I saw a lot of 7 round to 4 pin cords. Good luck

7-pin Flat or Round?
dumb question but Do the new Airstreams have a 7-pin round or 7-pin flat trailer connector?
I'm picking my new Bambi up next week (being built this week!) and need to install a 7-pin on my Fj Cruiser TV.
Thanks

All the new AS trailers use the now industry standard flat blade connectors. They may not be the best, but most tow packages include them. AS also is using standard color codes and pin locations, so with a tow package it is plug and play.
Enjoy your Bambi, I am enjoying mine.
