I have a stupid question, at least I'm sure someone will think it is stupid. My 2018 has the tow package with the TBC in the dash. My experience with these things is minimal having installed one in my Nissan Xterra and towed a 3000 lb camp trailer with it. When I wanted the trailer brakes to work I'd activate the controller by pinching the controls together. That one had similar controls to the one in my F150. Does the controller automatically apply trailer brakes when the brake pedal in the truck is pushed and the two levers just apply more brake power to the trailer when pinched together?

Thanks in advance.

LOL, no questions are stupid, but what you did is hilarious!

The levers are for setting the electric brake gain. After loading up, you get up to about 20-25 mph, then press the levers without pressing the brake pedal. If the brakes engage but do not lock up, you increase the gain until they do lock up, then back off the gain a bit.

This is the only time you press the levers. No, they will not apply more brake on top of what the controller applies while braking ,except the lever does applies full voltage, while using the brake pedal applies varying voltage determined by how much you depress the pedal. Do not press the levers except when you are adjusting gain.

Well, I'm glad that I made someone laugh. Did not know that. I honestly thought that the only time brakes were applied on the trailer was when I pinched the levers together. Then I really helped slow the rig down. Your answer is very much appreciated. When I get my trailer out next spring I will pay attention to adjusting the gain and leave the levers alone unless an emergency pops up.

THANKS!!

Absolutely incorrect. The lever allows you to apply the trailer brakes without applying the vehicle brakes... if you get in a situation where you're experiencing a loss of trailer stability, being able to apply (gently) the trailer brakes can help you regain control.

And, pressing that lever is proportional. The farther you slide it, the more you apply the trailer brakes. It definitely WILL apply more brake on top of what the controller applies. That lever is both for testing/adjusting the trailer brakes, and, also for applying trailer brakes in a driving situation where it is called for.

Watch the Lucille Ball/Desi Arnaz movie, "The Long Long Trailer." They have a funny scene where the dealer is teaching Desi how to brake the trailer using one. (Hint: In those days, the brake controllers weren't smart like they are today.)

And you are only missing the controller. It is a relatively inexpensive add-on, either Ford or aftermarket. If you need it, you should add it. Looking at around $200 bucks if you buy the part yourself, install it, and pay a dealer to turn it on - all factory ford parts.

Of the soap box...
I paid less than $100 for the OEM controller off of ebay, then purchased a Cable ($28) to connect a notebook to my truck in order to use FORSCAN (free) and set the computer to recognize and allow adjustment of the controller. Video on Youtube shows how to take the dash apart to install the controller which took less than 45 min.
