I just put a Tekonsha brake controller on a 2011 f150. I used the adapter from etrailer and there is no reponse from the controller no power light no brake nothing like it was not hooked up at all. I checked the fuses and they are all there and good. Any suggestions?

 

My 2012 F150 Ecoboost came with brake controller harness, fuse and relay that all needed to be installed prior to plugging in my Tekonsha P3.

 

I bought this truck used and no harness in the box so I ordered one from etrailer and installed. The fuses are in place but still no response.

 

Not the answer you want, but I believe Ford's built in brake controller can be installed by the dealer. Maybe by yourself ... dunno.

The main advantage is that it adjusts trailer brake output for vehicle speed. With my old truck the Prodigy needed to be dialed down when going in for gas or tootling around the city. Otherwise it would jerk badly. And then dialed back up at freeway speeds. Which I would often forget to do. Just about had a bad accident because of that, the trailer jack-knifed around the truck a bit during an emergency stop at highway speeds.

The built-in Ford product handles the speed correction for you, making it a safer brake controller.

 

Youre right man.

I dont have one installed, but i read a thread on here that guys were buying the brake controller from the dealerships, installing themselves, and then getting the dealership to "activate it" on the trucks computer. Usually took 3-5minutes.

Best part of all, the factory controller does compensate and adjust to all perameters of the truck at any speeds. This includes advance trac and traction control.

When Im back working, i plan on putting one in myself when i got the time.

Some dealerships were trying to charge 30min labor while others would let it go for free.

Again, check the thread.

 

Got a voltmeter?

There are 4 wires going to the controller. Unplug the connector from the controller and measure the voltage between the Black (+12V) and White (Ground) pins. No 12V? Check the fuse.

Also check the voltage between the Red (stop light switch) and White wires. You should get 12V when the brake pedal is depressed.

The Blue wire is the output to the 7-pin connector for the trailer brakes.

If the voltages check out I'd say the controller is bad.

I spliced my P1 harness to the Ford harness (too cheap to buy a Tekonsha harness) and mounted my P1 in the factory location. The only reason I have grabby brakes at low speed is because I'm running B1 boost.

 

Thats pretty informative man.

Im going to have to remember that one.
