4-Pole/7-Way Trailer Connector That Allows Both Connectors To Be Used Simultaneously


Do you have an adapter that will allow: OEM 7 blade to 7 blade AND 4 flat? I carry a truck camper and the 7 blade will power the truck camper and the 4 flat will power the trailer. I have the OEM dual outlet, but the covers prevent me from using both at the same time... Cheers

We've got exactly what you're looking for. Simply unplug the tow package harness from where it plugs into the rear of your existing 7-way (which likely looks like the # HM40975 ), and swap your 7-way for part # C55774. This will provide a 7-way and a 4-pole which can be used simultaneously.

Or, you can also install a dedicated 7-way in the truck bed using something like # 20110

I've linked to some typical installation videos for you.
