Retrofit factory integrated brake controller
 

I would like to install a factory integrated brake controller into my 2003 f350. I am aware that they were intended for 2005+ super duties and that my truck doesn't have the pre-wired connections and appropriate master cylinder with brake pressure transducer. But, I was wondering if anyone has a pinout or wiring diagram of the integrated brake controller and adjoining wiring.

I am aware that the brake controller's function is somewhat dependent on input from the trucks computer, because it requires a trip to the dealer to activate it on 2005+ trucks that didn't originally come with it. I know that it requires a master cylinder brake line pressure sensor reading. Maybe if I had a pinout or diagram, I could figure out how to rig it to work with my truck.

SSCULLY made a post years ago about it here:

If that be the case, then this retrofit might not be that difficult....

Thanks a lot to anyone that might have something.

I added TBC on my new 14 truck.

Exactly what year & model are you looking for as far as the diagram?

Hey man, haven't seen ya in a while... you been doing ok? Is your motor still feeling all that extra power you got from taking the intake silencer out?!! haha

I have a 2003 F350, but I need a diagram from a 2005-2007 super duty with factory integrated tow controller. I need to know the required inputs to the brake controller so I can figure out how to work them out with my 2003 truck. (which "technically" is not compatable)

Shoot me your email and I'll send over some diagrams

Sent. Thanks a lot!

Looks like I'm just gonna have to scrounge around and find a Brakesmart controller. I was already looking for one, but I was hoping that somebody had done this conversion before, or knew where to start with it. Thanks to Patman and SSCULLY.

What's wrong with getting a Prodigy? It's an excellent controller.

Prodigy controllers (and all other inertia controllers) have an accelerometer or pendulum in them, that sense the truck slowing down, and attempt to add trailer braking in proportion to its perceived deleceration. They are jumpy jerky, and they don't always work well. There's a delay between pedal push and the actual brake controller coming on. They sometimes don't activate during certain circumstances such as a slippery road. They can't tell you are trying to slow down if the truck doesn't actually slow down first. Steep hills give them fits. The factory integrated controller doesn't really compare to these kinds of controllers, cause it doesn't work the same way.

The factory integrated controller has a pressure transducer on the brake master cylinder (or abs module). It knows exactly how hard you are pressing the pedal and applies equal braking force to the trailer. Even if the truck is sliding, or there's a heavy load behind, or going up a steep grade, it still presses the brakes on the trailer as hard as you do.

The Brakesmart (and MaxBrake) controllers I mentioned works very similar. They also work by sensing actual brake pressure from a transducer tee'd into a brake line. They are the best, fastest, smoothest aftermarket controller, but the company doesn't build them anymore... :(

Just in case anyone else is interested in this "conversion" and why it won't work, this link gives a dumb'd down description of the operating principles of the factory brake controller. It also explains its required relationship to components in the 2005+ trucks that the older trucks either don't have, or differ in operating principle.

I didn't realize how many significant differences there were between the 2004 and 2005 super duties wiring and computer components.
