I have a 2015 RTL with a 4 pin flat harness. I purchased a 2010 RT 622 trailer with a 9 pin round connector. I have searched & read previous posts for the past hour. Is there an adapter that can be purchased that will work in this situation? Any help is greatly appreciated.

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Having been through the same and similar with other owners, these are my suggestions.
1) Ensure your trailer has the ground wire update.
2) Purchase a new wire harness from the hitch to the connector where the tow bar fastens to the trailer chassis.
3) On Amazon, purchase a 4 pin square pigtail, AND a 4 pin flat pigtail.
The ground wire update on our trailer was a factory update according to our dealer when they ran the VIN. No charge for that. The new wire harness was inexpensive and updates from the round style connector to the 4 pin flat. Again, inexpensive are the pigtails. I soldered ours and protected with heat shrink. Ultimately, I joined the square trailer harness to my new adapter harness. Wrapped in tape to provide a seal. I also applied silicone dielectric grease to prevent corrosion. That wrapped connector was stuffed into the trailer tow bar. The length left exposed was correct to reach the Spyders connector and not foul the tire.
So now ours is setup as 4 pin flat on both the Spyder and trailer. On the Spyder side, I merely made a second pigtail. Essentially, if needed, going back to 4 pin square is a matter of unplugging the adapters.

As PMK says. When you make the change you will disable the amber turn signals and change the red ones to turn/signal. I've never used the tongue harness adapter cable but I think that it does that for you. I also think that the trailers with the 9 pin connector may have had backup lights also. Those no longer will be functional.

There is a trailer mod too where they remove the amber lens bulbs and install tape covers over the bulb socket openings, but why bother.
