Question:

Do you have an adapter? 7 pin Plug connector with a brake dummy load / fake out out the backup alarm to 4 pin flat four. The backup alarm goes off in reverse when using my non brake trailer with flat four plugin. Thanks in advance

Hey Thomas, we have just what you need with the 7-Way to 4-Way/5-Way Trailer Adapter for Vehicles with Lamp-Out Sensors Towing Trailers with LEDs # C35FR. This converts your 7 way round to a 4 way flat or 5 way flat (common on boat trailers) and also has built-in resistors to simulate a load to reduce the likelihood of your tow vehicle having any false trailer warnings.

We also have this in a 7 way round to 7 way round adapter in case you need that as well # 20142.
