Question:

Hello, am trying to figure out what i need. On the DC to DC tow to trailer connection. On the trailer i have a rectangular 2 port connection with a positive and Negative. On my 2021 Tundra i have the rectangle with 4 prongs. What do i need to connect the two optimally to charge the trailer?

@MarcusR I did just see the pictures you sent over. It looks like you have a standard 4-way on your vehicle but then the trailer needs like a quick connect style connector like what winches use like the part # SWC60015-8. That makes me think that you are trying to power something that draws a lot of amperage like a winch which you wouldn't be able to do through a 7-way. You'd need a wiring kit with much heavier gauge wire that connects directly to the battery like the # BDW20207 if that is the case. Does the trailer have a winch?
