Ford Super Duty (1999-2016) :: Trailer Has Running Lights But No Turn Signal Or Brake Lights
2013 F250 XL with factory towing package.
My camper and boat trailer do not have turning signal or brake lights when plugged into the round seven pin trailer connector. I have tried both the connector in the bed and under the bumper. I've also connected the trailers to other trucks and the lights work fine so I know the problem is in my truck.
Ford Super Duty (1999-2016) :: OEM 7 Way Trailer Connector Broken Off?
Well, it seems the cover on my trailer connector got broken off. The cover locks the trailer plug into the truck side. The connector on the truck is/was supplied by Ford. Now the dealer say NLA, only 2005 and up. Truck is 99 F250 SD. Plug is 4/7 way. Where can I locate a direct plug-in replacement? I do not want to be cutting and splicing.

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.
Ford Super Duty (1999-2016) :: 2005 F250 - Trailer Running Lights Always On
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.

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.

2004 ford f 350 super duty, 6.0 Liters international diesel, 4door, 4x4, long bed, dual rear wheels. Over 200,000 mileage. I have no power to the trucks brake lights and no power to the tow plugs trailer brake lights, which is the center left and the center right tow plug blade style contacts, while using a 12 volt test light! All fuses are showing good and I replaced the brake switch at the brake pedal, and I also replaced the towing plug with the short wire and connector at rear of truck which is under the rear bumper and the frame mounted tow hitch bar
- Are there any relays that control the truck brake lights and the trailer brake lights ?
- If yes where are the brake relays exactly?
- Have I missed or not done something else to correct the problem?
Ford Super Duty (1999-2016) :: 2006 F250 XLT - No Power At The Connector Of Under Hood Lamp
I have a 2006 F250 XLT 6.0 diesel. I bought last month to haul my fifth wheel. Looking for the wiring diagram for the "under hood lamp". I have no power at the connector of the under hood lamp. I have checked all the fuses in both locations (battery box and central junction box) and did not find a blown fuse. The under hood lamp is not listed on the the central junction box fuse and relay posting in the owner manual. Is it controlled by something else?

A week ago last Saturday I bought a 2006 F250 Lariat Crew Cab with the 6.0 and 4WD. The truck is really clean and only has 68,000 miles on it. Here's my question: I needed to tow a boat today and I discovered I have no power, at all, at the trailer light plug receptacle. Nothing at the 7-pin nor the flat-4. I looked through the manual and checked every fuse that had the word trailer associated with it and I can also feel the turn signal relays clicking with the flashers on.
Am I missing something really simple or do I just need to follow the wire harness from the back and look for something that is not connected? It seems kind of weird for it to be just....dead.

Was moving a boat on a trailer with surge brakes and found I could not back it up. Found that I had no power on the center pin on the round 7 seven trailer connector.
When backing this type of trailer the back up light power opens a solenoid that keeps the brakes from working in reverse. Don't know how long its been like this because this is the first time I moved this trailer. The question is where is the fuse and or relay for this. The back up lights on the truck do work.

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...

I have a question about my new to me 2006 F-250 CC, 4x4. Resource the 12-volt accessory supply wire that goes to pin #4 on the 7 pin trailer connector? We have interior lights in our enclosed race trailer and it's a bit of a pain to have to turn the key on to use the lights. Just don't want to run a direct fused wire from the battery to the plug if I don't have to.

The rear tail lights on my truck have been out for a while now. I wasn't doing much driving at night so it wasn't much of a bother but the new job is getting me home a little later and having to drive with my hazards on is getting old fast.
My radio wasn't working either and I disconnected it a while back hoping maybe it had something to do with my lights shorting out but no luck. It remains disconnected. Just in the past few days my front running lights have went out as well.
I've tested all fuses multiple times (and replaced a couple of them) and checked and replaced bulbs. My brake lights, headlights, dash lights and hazards all work fine. I have the trailer light hook up on the rear bumper and disconnected it at the wiring harness as well hoping it was the problem but it wasn't.
