Question:

Hello, is there by chance a 7 pin flat to 7 pin round pole pin adapter that is listed on the site that I may have missed or is this something that I would have to have custom made?

Hello Warren, thanks for reaching out. We may have an adapter for you. If your trailer is a 7-round and your truck is a 7-pin flat, you can use the adapter part # 47595. That or what a lot of people do it replace the 7-round with a standard 7-flat like part # PK12706. This way no adapter would be required.

If the scenario is the other way around and your truck has the 7-round and your trailer is a 7-flat, I am afraid there is no adapter for this. The best option here would be to swap out the plug on your truck for a standard 7-flat.

If you want to look into it let me know what your tow vehicle is and I can see what your options are.

Hey Warren, did you end up trying the adapter or swapping the plug on your truck or trailer? Knowing which route worked could really help others facing the same wiring setup.
