Upgrading A 5 Flat To A 7 Way And Where To Connect Reverse Solenoid Wire

Question:

I am wanting to change my 5 pin flat plug to a round 7 pin plug to fit my 2017 ford Expedition. My trailer has working surge brakes and a reverse solenoid. My question is can I connect the solenoid wire on the trailer to the blue brake connector on the round plug. Please advise and thanks!

The reverse solenoid will be wired to the reverse light circuit on your vehicle. You can use a 7 way plug like # PK12706. We also sell 12 gauge jacketed 2 wire by the foot in part # 12-2-1. The reverse lights are generally wired to the center pin on the 7 way plug # PK12706. I have included a diagram which the locations of each circuit.
