Ford Super Duty (1999-2016) :: 2012 F550 - Location Of Trailer Brake Controller Harness
Jun 4, 2013
We bought a 2012 f550 chassis and had a utility bed outfited. As far as I know the truck does not have a tow package (major F-up). They did install a receiver and electric in the rear. The 7 way pin in the rear does have the appropriate wires (including blue). I can not find the harness in the cab under the dash. I have looked near the radio where I have found the harness on our other trucks. I specifically looked for the red white and blue wire under there. Where is this harness? Is the harness still in the cab even without the tow package? This will be for the old school plug in controller, not the ford intergrated contoller.

I recently purchased a 2011 F550 Super Duty with a flatbed mounted on it. Turns out, the trailer wiring harness is totally screwed up and I am getting tons of shorts whenever it rains. Going through it front to back, we are finding multiple problems like missing fuse box covers, damaged fuses for starters. The Ford dealership in Texas that did my prepurchase inspection for me totally missed all of this, so i am stuck holding the short end.
IN the rear of the truck we detected shorts in several areas. One of them is in this adapter pictured along with this. Is this a Ford part, or does it appear aftermarket? Is it just an adapter or is it more than that? I am just now getting to l know this truck more specifically. given the date of manufacture on the label it would seem to be from Ford??? Part # is 99-004 and 71-012-A...

I've just bought a new 2016 SD xlt. The only extra I wanted that is missing is the factory trailer brake controller. The dealer told me it had to be programmed. I was expecting plug and play and planned to do it myself till they told me that. Is this true?

Where I can find a good used or a good deal on a new factory trailer brake controller to fit a 2006 F250 Diesel Truck?

I tow a 5th wheel with my 2014 F-250 that has an factory TBC. I just installed Electric over Hydraulic disc brakes on my 5th wheel and was trying to see if there was a setting I needed to change on the TBC to tell it that is now E/H versus E. In the Information section of the dashboard display it talks about the controller actuating electric drum brakes but the manual talks about it being able to do electric AND E/H. What I need to do here...if anything?

I am looking at getting my new truck, my 05 F350 6.0, with factory trailer brake controller, all set up for a gooseneck. I was wondering if there was an OEM kit to add a trailer connection plug to the inside of the bed? If there is, what are the part number(s)?

The pigtail from my bumper mounted 7-pin to the factory connector is all hacked up from the previous owner so I'm looking to replace that pigtail. Also wondering if there should be 2 connectors down there to add a connector for my gooseneck or do I need to splice another universal 7-pin into the bumper light pigtail? Also, is there another (preferably slightly cheaper) option besides e-trailer for such a connector?

I'm still fighting tow harness problems on my '01 F 250. I started by replacing the 7-way pig tail with a new one which didn't work. Then I undid all the butchering of the harness that was done previously. The factory harness had scotch locks all over it that were used to splice in a 6-way and a 7-way into the bed. I liquid taped all the nicks in the wires. Then I checked for power at the factory harness end where the pigtail plugs in. I have park/running lights, and one of the ports flashes for the left turn signal/flashers/stop lamps. I got rained on before I could check further up the wire. If I have no power to the wire further up is there another place to check?

Any info if the "Aux" terminal on the trailer harness wiring on '01 F250s is for reverse lighting? I'd like to put some on my stock trailer. Also, is the "12v" terminal feed switch operated or hot always?

My 08, when I connect my 7-pin trailer up, bouncing down the road that message and tone CONSTANTLY going off....drives me nuts! I have went thru the wire harness 2x now, cleaned all the contacts, etc. Any other thing short of a 12 gauge? When it does pop on, the controller starts flashing...I've reached down a few times and manually hit the brakes and it still hits em so whatever it is, I feel its very minor or whatever....just don't know where to go now! All contacts have been cleaned good as well.

Any limited number of lights the factory trailer harness on the truck can tolerate? I'm looking to add some extra running lights on my trailer, also want to put a couple of lights on each running board on the truck, they will be tied in with the trailer harness since it is not monitored by the BCM. I did a search on this a few different ways and couldn't find anything.

I am looking for the location of the fuel pump relay for my 1999 Ford F550 V10 4WD Gas truck.
I have replaced the fuel filter and fuel pump. When the key is turned the pump gets juice and 2 seconds later is not getting juice. No lines are coming into it, so it's not getting up to pressure and shutting off.

I have a 2006 F250 and my 7pin and 4 pin connectors are just hanging loose. I'm not sure what happened to the factory bracket. What is the part number for this bracket? Also, where does it mount to? I looked under the truck and couldnt tell where the factory one mounts.

OK, so I have the brake pedal downshifting, but there is no real exhaust brake. Can I have one installed, like the latter model 2015 or even the 2016, with the button?

I am trying to figure out where the relay would be when i look online for the map of the relay box under the hood it says nothing of a horn relay. I don't have a key fob for the doors to unlock so I wouldn't think its tied to the computer. Should mention nothing happens when you hit the horn also fuse is fine. No power at the actual horn when i hit the steering wheel(horn)....

I am having an issue with the under dash plug for the brake controller on my 2001 Ford F250 Super Duty. I plugged in my Curt Brake Controller and figured all was good.
As usual with anything I do it isn't that easy. There is no power to the controller or the plug.
Is there a specific fuse I should check or even look to see if it has been installed because apparently this truck never had one installed even though it has a 7 blade plug installed and is plugged into the wire harness in the rear.

First, need a wiring diagram for the outputs on the back of the brake controller module? I want to check and see if there is a problem with the connection to the rheostat. I can activate the trailer brakes with the slider bar but not with the brakes.
Second, where I can get a new OEM controller that will replace my old one if I can't "Cypher it out"?

I 2000 f250 throughout a few years.
Anyways, I recently aquired a tekonsha voyager (for free) and went to install it, but have run into a problem with the installation.
I searched to find a wire color guide to figure out what wires are which on the under dash connector, but cannot find the answer I'm searching for.
Currently I have a red, green, blue, brown, and yellow wire on the underdash connector, while the tekonsha only has red, white, blue, and black. (I know what colors do what on the controller, but am completly lost on the under dash plug, and can't trace it back without tearing out the entire dash assembly.
