Seneca Electric Brake Controller

[Fordfixer1]

On a 2017 Jayco Seneca has anyone installed a trailer brake controller. If yes was it pre wired under the dash and what color are the wires to supply the signal to the 7 pin trailer plug?

When I've installed brake controllers on various pickups I've owned, they typically were 'plug and play'. I'm guessing no one makes a 'plug n play' for the Freightliner chassis? Have you just used the generic harness and hooked up the proper leads individually?

Great information Guys, however the tow dolly I've purchased has a brake controller on it the get's it signal from the 4 pin connector by way of the brake lights. I can always install the brake controller later if this system does not work to my satisfaction.
Thanks again.

Our Seneca has both the round 7-way and rectangular 4-way connectors out back. You should be good to go too.
