To install the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 in your 2019 Jayco Seneca on the Freightliner S2RV chassis the wiring is behind the kick panel in the drivers compartment. There is not a connector on the wires, they are simply terminated with tape. You will connect those with the wiring pigtail that is included with the brake controller.

You can use the longer Pigtail # 7894 if you wish to move the brake controller to the right side of the steering column. This pigtail is 34" long versus the 12" pigtail that is included with the brake controller.

Wiring should be as follows but be sure to verify this on your Seneca.

White - Ground
Red - 12V Constant Power
Red/White - Brake Signal
Blue - Brake Controller Output
