Expert Reply:

It sounds like your trailer has a 7-way round pin connector. For an adapter, I'd suggest part # PK12727. The adapter would plug into the existing 7-way on your truck, and provide a 7 round pin female connector for the plug on your trailer.

You might also consider removing the existing 7-pin connector from the trailer, and replacing it with the 7-way blade plug like part # A7WCB. The 7-way round pin is getting fairly close to being obsolete. The 7-way blade connector is much more prevalent.

I'll link you to our FAQ article about trailer wiring. I hope you'll find it helpful.
