Hey, Joe.
I just want to make sure that I'm understanding your question. Are you saying that your truck has a standard 7-way and is equipped with a Curt Venturer brake controller but the trailer you recently got is wired for a 6-way round pin? If that's the case then the TowSmart 7-Way RV to 6-Way Round adapter part # TS22SR is what you will need to get.
If that's not what you are needing please let me know. You can also reply to the email with some pictures of the plugs that way I can see exactly what you got.
