Why Won't 7-Way Connector on Trailer Fit Factory 7-Way on My New Silverado
Products Featured in This Question
Question:
Need help. Had this installed on my trailer but it's not plugging into the truck's 7-Way. Like it doesn't fit. Confused. What am I doing wrong? 2022 Silverado 2500. Thx.

This is an interesting (extremely frustrating) issue we've recently discovered with a lot of the new GM trucks, specific to the Bargman 7-Ways like the part # 54006-057 you mentioned having. I can at least assure you that you're not doing anything wrong.
The problem is with the molded "fins" present on the factory 7-Way for these new models, which prevents the Bargman 7-Way from properly seating into the connector. There isn't really a fix for this beyond either replacing the factory 7-Way on the truck or getting a different connector for the trailer, unfortunately.
Since you just installed the trailer side, the simplest solution is probably to just replace the truck's 7-Way with the Hopkins # HM40975. This will be an easy, plug-and-play installation. If you wanted to replace the trailer side instead, the Pollak # PK12706 will be the best option and is actually what GM suggests because Pollak is who manufacturers the factory 7-Way on their trucks.
I've attached a couple install videos that you can check out as well.
