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?
View 2 RepliesI 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.
View 4 RepliesI 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)?
View 9 RepliesThe 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?
View 3 RepliesI'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?
View 2 RepliesI 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...
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.
View 8 RepliesWe 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.

So the truck drove fine yesterday had zero issues... I used my auto start as I do every morning in this cold weather, get into the truck and shift from park to drive and its like it does nothing. I can free rev in N,D,1,2. Reverse works great.
I tried switching from 4wd to 2wd, no change. Reverse works just fine. No noises, codes or anything, just doesn't want to engage...
I am assuming I have a 4R100. Could something electrical cause this? I am thinking its mechanical, but hoping someone has ran into this before.
Literally no way I would have known the trans was going bad... It's always worked fine. Tranny fluid is full, I tried unplugging the battery waiting and plugging back in, no dice.
I recently had need of replacing my left exhaust manifold on a 2000 F250 4 x 4. I removed plastic inner fender well. Now I have a two pin harness with both white wires. One is white with red stripe, the other is white with black stripe. The harness is round with a locking square on one side. The harness is located about 10" from bottom of inner left plastic fender panel. It has 2 mounting pegs. Where the heck does this connect?
View 13 RepliesI'm trying to find out what the two connectors in the image are.. I've looked through the manual that I have and searched around on the web and find nothing.
They're on a 2015 F250. "upfitter" switches were installed from the factory.
I have a 2005 Ford F-250. I have checked power to the rear harness and all is good except for the tail/running lights.
Is there a fuse for the tail lights? I have checked the manual and don't see one called out. And the relays under the hood are labeled stop lights/turn signals and those are working fine.
I will see if I can trace the brown wire from the rear harness backwards, but it may be a simple fuse.
I have a 2005 ford f250 with the factory installed brake controller and towing package,until recently all was well,I tow a fairly large travel trailer and last time I hooked the trailer to the truck I noticed the running lights on the trailer were lit, I checked to make sure that I did not have the parking lights turned on or the headlights. I did find posts about the running lights not working and was surprised to find there is a relay somewhere on the central junction fuse block that was integral to the cfb and not user serviceable. Could my problem be that this relay failed in the closed position or am I not going in the right direction in my quest to find this problem. Also looking for a diagram of where this relay is located on the central junction fuse block? I would also consider doing a work around solution rather than having to replace the entire fuse block.

View 1 RepliesI am having a problem with trailer lights and an 03 350. When the truck is in reverse the fuse for travel trailer running lights and tail lights blows immediately. Changing plugs on the truck did not work. Truck has been hooked up to 4 other trailers including another travel trailer with no problems. Our travel trailer has been hooked up to an 08 and a 2011 truck with no problems. Fuse 38 20 amp. 7 post rv plug.
View 3 RepliesI have (2) 2014 f250's both have given the trailer disconnected message randomly from the day they were new. Dealer says everything is with in specification. I just live with it now but something must be wrong with the design. Only does it when no trailer is connected an might be worse when it rains. Might have to hit the ok button every 10 minutes so on bad days.
View 14 RepliesSo the other day 2/3/2014 my dad and I went out during the snow storm for the people that needed assistance. That day I pulled a 95' RWD dually with a 4 car open trailer and pushed 4 people from one location. Then after I went to assist the tractor trailer driver. My truck is a 2002 F250 super duty 5.4L with 4:10 gears. I got him unstuck then pulled him a 1/2 mile up a hill.

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?
View 6 Replies2010 F250 Lariat, cab and a half, PSD. 5600 miles.
Sunday I started the pickup and received "trailer brake module fault" in the message center. I wasn't pulling so wasn't too concerned - hit the reset and continued on.
Sunday night I started the pickup again and received the same message followed by "check brake system". I also lost illuminated gear selection, the traction control active symbol was displayed and the traction control "off" (PB) was illuminated. After several attempts it reset, everything returned to normal and I was able to get home without incident.
Monday morning it wouldn't start. It indicated "trailer brake module fault", "check brake system", traction control active and off, no gear indication, the odometer indicated "-------" and it did not react to the key in the start position.
Tuesday morning I attempted to start and it was the same as the previous attempt. I noticed that the theft prevention appeared active (flashing) so I removed the key, locked the doors, unlocked the doors, tried again - no joy.
I kept trying while holding my mouth in different positions and finally by the grace of God it fired. I delivered it to the dealer.
The dealer called yesterday afternoon and reported that everything is a result of a bad trailer brake module. The new one is to arrive today, they will install and everything will be peachy.
I asked if they could just unplug it and reprogram the truck to believe it never had one - the service writer said it can't be done, different piece parts on trucks with or without trailer brakes.
I really have no choice but to push the "I believe" button and carry on but I am slightly concerned. The fact that the trailer brake module can cause catastrophic failure doesn't seem too cool, I don't have a real warm and fuzzy feeling associated with venturing far from pavement, reliable communication or alternative transportation.
In the meantime I suggest that no one take "trailer brake module failure" lightly.
My husband and I bought a 09 f-250 with 58000 miles. It used to pull our travel trailer with no power issues. Now the rpms go up & the power goes down. It never gets hot nor any lights come on. It's been in the shop twice. The first time nothing was found. The second time we were told it was dirty fuel filters. The truck only has 70k miles...
View 2 RepliesI've got an intermittent Trailer Wiring Error message that started appearing with a trailer connected on my '11 F250.
Brakes and lights work OK on the trailer, I thought I had read on the board here that there was a TSB for this, but I cannot find it.
