On 2010 150 had running lights for approx 1 year on both 4 wire and 7 wire then none. Nothing changed, Checked fuses, all ok. Checked on back side of plug, nothing. Everything else works.
View 14 RepliesI just bought an electric tongue jack for my utility trailer. Rather than mount a battery on the trailer, I bought a jack that has a 7 way plug, so you just plug into the truck in order to power up the jack. However! My '13 Platinum F150 appears to have a very smart 7 way plug. If I plug in the trailer, everything works fine on the trailer.
If I unplug the trailer and use my tester to check the power inside the 7 way plug on the truck, there is nothing. So when I plug in the jack, which only has 2 tabs on it's 7 way male - positions 4 and 1 (positive and negative since they are red and black) it does not turn on. I wired direct to my battery from the jack 7 way plug and jack works fine.
So I'm guessing that the 7 way plug is not powered up until it senses a trailer is plugged in somehow? Is there a way to override this? Also the 4 flat on the truck was dead when I put the tester to it as well. Maybe same thing? If not, I'll have to hard wire the jack into the trailer wiring harness as a work around I suppose.
I have a VW Touareg hitch installed by the dealer. I tested the plug this weekend and found that I do not have running lights. Turn signals and brakes work fine. I discovered that my boat trailer uses a 5 pin flat plug to the round 7 pin that fits into the Touareg hitch receptacle. I believe most trailers use a 4 pin. Is there a fix?
View 10 RepliesI have a 2011 Ford F-150 XLT. I did take the fuses out of the glovebox and installed them. So trailer lights and blinkers work fine. I just purchased a small teardrop tailer. My problem is that the trailer lights are always on when plugged into the truck.They are on even when lights are off and key is out.
I am assuming that the problem is with the wiring of the trailer harness but I wanted to ask here first in case the problem might be with the truck. I have never had a trailer so I am unsure if the 7 prong plug is always hot. Obviously it is on my truck. Is this way it should be?
Ok we have a 2012 F-150 and are trying to hook up a 16ft trailer but have no lights. We know the trailer wiring is fine (works on other vehicles) but we have no power at the 4 pin trailer connector. We have checked the fuses and all are fine. Having this problem on a 2012?

I've been looking for the fuse that runs the trailer running lights and couldnt find it and it got dark on me.. Does anyone know if its under the hood or inside the cab? I blew the running lights fuse hooking up the trailer while the lights was on...
View 13 Repliesluckily about 5 minutes from home my trailer running lights AND the lights on my dump truck body stopped working. i assume they hooked the lights to my dump body to the trailer lights. i was towing an old trailer that has electrical issues so I'm sure that caused it. Under the hood there is a 30 amp fuse #26 that i think is the culprit. (All the other similar fuses are shiny and that one is kinda black). I've never bought fuses like this before, what type is it? it's a big square one. Are they available at auto zone? Does the whole thing pull out and do you need a special tool for it?
View 3 Replies03 f350 7.3L. Have no power for the trailer running lights at the connector end. No power when the end is split and no power at the next connector above the spare tire. I have power at the fuse (38) and the fuse is good. What is the best connection to check next? Is there a common culprit that might cause this problem somewhere? I know 3 more connectors are in the frame by the fuel tank but pretty much lose track of which one might have the wire for the trailer.

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.
on my '13 STX, when you press the "unlock" button on the remote, the running lights come on and stay on for a while. It does this when I open the door as well. Is there a way to disable this? I really have no need for this feature and it will burn the bulbs out sooner.
View 12 RepliesI have a 2010 f150 super crew, last night when leaving my baseball game I was shocked to find my running lights and my regular beam lights don't work. My high beams work fine but nothing else. I'm pretty sure the lights are an after market light, but I'm not positive since I purchased it used. I looked in manual to check for a fuse issue but I don't see anything regarding the headlights.
View 1 RepliesOK, I have looked everywhere I can think to look and can't fined anything on this. Dash lights how do you turn them off with the engine running. This is on a 2012 f150 xlt.
View 4 RepliesI have a 2004 f150 fx4. My running lights on my trailer will not come on. Brake lights work, turn signals work, back up lights work. Had my boat mechanic check the trailer and that showed that the lights work fine. So I started checking fuses on the truck. Fuses all looked good. Then I went into the Auxiliary Relay Box in the engine compartment on the left fender. In the spot marked Trailer Tow Park Lamps (R201), theres no relay. R202 is for the Fog lamps, same relay. I pulled the Fog Lamp relay out and went to put in R201 for Trailer lamps, but there's no contacts in the R201 slots. The relay goes in with ease and just falls out. No contacts. Whats going on?

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?
My father has a 2009 F-150 with almost 25,000 miles. (he leaves it in garage and polishes it weekly) He just purchased a new dual axle trailer with electric brakes and led lights. When we hook up the trailer and press the Brake, turn signal or hazards, we blow a under hood fuse (48 if I remember correctly). When connected to either of his other 2 trailers, everything works and no issues. When I connect my 2014 suburban, the new trailer works perfectly. He does not have a brake controller installed on the F-150 yet. It does have the 7 pin and 4 pin plugs under the bumper.
View 7 RepliesHooked up to a bumper hitch trailer tonight with my 13 F350 and didn't have any lights but the brakes worked. Tested the bumper hitch trailer connector and there was no power on any terminals, with the tester still connected to the same ground I checked the trailer connection in my bed for my gooseneck trailers and everything was working. Just to check the trailer I hooked up my wife's 2015 F150 and all the lights worked. Can't figure out why my gooseneck connection works but not my bumper connector, also looks like my license plate lights are not working either.
View 14 RepliesI got in a work truck yesterday, sat down, put my seat belt on and started the truck. Just as I did that another employee drove by and waved, all I could do was nod back at him because my hand was still starting the truck. This took my attention away for a split second, then as I put the truck in gear, my foot still on the brake, I noticed that the tachometer was pegged and the engine was racing. I instinctively pushed harder on the brake pedal, then looked down to be sure that I was pushing on the brake pedal and I was. Right then then rear of the truck started shaking violently and as fast as I could I turned the key off and put it back in park. This all happened in about 1 second, maybe 2.
The shaking was caused by the sheared off driveshaft. And it was sheared off because the center section of the rear differential had broken the spot welds that hold it and place and rotated on the axel housings. It is now pointing upward towards the bed of the truck. Have a drive by wire truck run the engine at wide open throttle with no input from the pedal? 2010 F150 4.6L...
I have a 2012 Ford 4x4 crew cab 150 xlt. 15,000 miles. When pulling my dump trailer I was stopping to turn and the transmission disengaged. Once I turned the corner coasting the transmission kicked back in again. During this happening pushing the gas did nothing but rev up engine. My dealer said if this happened that a warning light would of came on or a wrench would appear on dash but it didn't. He said then it didn't happen. This happened 3 times in 10 miles of driving. I had it in tow mode.
View 4 RepliesToday while towing a 10ft trailer with a golf cart my truck seemed kind of under powered.It has the 5.0 with 3.73 rear end.When I got to where I was going I looked under my truck and there were spots all over the rear end and axle and frame that looked like oil or transmission fluid. I cannot find any noticeable leaks. The air temp today was 100 and the transmission gauge stayed around 200.
