4 Flat to 7 Pin
When you're towing heavy loads behind your vehicle, safety should be your number one priority. That's why trailer connector kits are one of the best investments you can make to improve your driving experience. With the proper 7 pin wiring attached to your ride's back end, you keep other drivers aware of what your intentions are when it's hard to see them on the road. Whether, you're stopping short, changing lanes or cruising along at a safe speed, trailer wiring kits are essential to ensuring you get to your intended destination happy and without any unnecessary mishaps along the way.
This trailer connector kit converts a 4 pin flat car connector to a 7-pin (AG or heavy duty) socket.
