Parts Needed to Install 7-Way Trailer Connector on 2017 Kia Sorento

Question:

My trailer has surge brakes with an electric solenoid to disable them in reverse. Will this setup incorporate the power from the tow vehicle's backup lights to energize the solenoid?

The type of trailer wiring connector you are looking for is a 7-way blade trailer connector which we can easily help you install on your 2017 Kia Sorento!

You will need to start with a 4-way (if you do not have one). For that you would want the # 118583.

Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way.

If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller.

For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.

Yes, the adapters mentioned can activate the reverse lock out solenoid of your surge brake setup. You'd need to run the purple wire of the adapter to the reverse light circuit of the vehicle to activate this.
