Recommended Parts to Add 7-Way and Reverse Circuit for Towing a Boat Trailer

Question:

looking for a boat trailer adapter plug that utilizes the center pin for the backup solenoid in a 5-pin system, I have a four flat coming out of my expedition The boat trailer has a seven round that will plug into the back of the expedition. The part I need is the adopter for the back of the expedition.

Thanks for all of the details Henry!

I recommend picking up the Hopkins # 37185 and the Curt No-Drill Bracket # C57202 to get the reverse signal from your Expedition to your boat trailer. All you have to do is plug in the 4-Way to your currently 4-Way, connect the ground, and then connect the purple wire to your reverse signal.

The Hopkins connector is one of my favorites because it upgrades your 4-Way to a 4-Way and a 7-Way so you don't have to remove the adapter when you need to tow a trailer that only has a 4-Way connector on it.
