Brake Controller Recommendation for 2018 Jayco Seneca Motorhome

For a brake controller I would recommend the Prodigy P3 Brake Controller part # 90195 for your 2018 Jayco Seneca. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well.

That we are aware there isn't brake controller wiring on your RV so you'd have to hardwire the controller. You will need to first locate the stoplight switch under the dash using a circuit tester like # PTW2993. This wire will only show power when the brake pedal is pressed. This is where the red wire from the brake controller will connect to.

The blue wire from the brake controller will then be connected to the pin on the 7-way connector at the rear of your truck that is designated for the brakes.

The white wire on the brake controller is for ground and can be secured to any clean, bare metal surface on the vehicle.

The black wire on the brake controller is the 12V power and will be attached to the positive battery terminal using a circuit breaker. If you have 2 to 4 brakes on your trailer, you will use a 20 amp circuit breaker like # PK54220.

If you need additional wiring to reach this length, you can use # 10-2-1, which is sold by the foot. If you need additional blue wire for the brake controller, you can use # 10-1-1.
