My 08 F3 50 seems to be turning the lights on and off by themselves throughout the course of the evening and the day currently I am disconnecting the negative cable trying to trace back a bad ground I'm not exactly sure what I'm doing

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.
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.
99 f350 7.3... All lights working but running lights wont go off....
View 1 RepliesI just bought my 2016 super duty about 2 months ago, really liking it, got a couple questions- How do I turn off daylight running lights? When head lights are on, instrument cluster lights come off and on according to outside light levels, can I turn off this feature?
View 1 RepliesJust the other day I fired the truck up and turned the lights on and my headlights came on but my gauges didn't light up. I figured I probably had a blown fuse or something so I didn't bother checking it immediately and decided to drive home anyways and on the way home I got a phone call saying that my running lights weren't working either. Front or rear. Still have brake lights and turn signals but no running lights. I've checked all the fuses and none of them are blown and I'm going nuts trying to figure out what is wrong before I get a ticket. I'm tired of lightly holding the brake as I pass by cops at night. What could be causing this issue?
View 11 RepliesI 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 5 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.
View 3 RepliesI am a trucker at heart and I like to add running lights to my running board / step bars. As far as installation of the lights, done it several times, no problem there. However in the past, I have just ran a wire back to the trailer plug and used a scotch lock / snap connector to feed the running board lights.
If I do the same on a 2012, will that cause havick with the computer? Most likely I will be running 7 lights, all 3/4" diameter LED style. If this isn't' the best solution, then where to get power for marker lights.
No straight answers found yet. It's just the running lights that get stuck on.
I don't have auto lights, and after a period of a minute or 2 the lights pop off. There must be a relay sticking somewhere.
Looking for a diagram that shows where the relay for running lights is located?
I Have a 2002 F 250 That I recently changed the fuel pump. and now I'm having a tail light problem. when i start the truck, my tail lights and plate lights comes on (dim). if i turn my head lights on the truck stalls out. if i step on the brake or put the truck in reverse it stalls out. if i put it in drive it runs just fine. i checked my fuses and relays and the problem is still there even when the relay and fuse for the lights are out. when i turn the truck off all the light go out.
can't seem to find any info on this problem anywhere.
I recently got my truck back from the dealership 04 super d 4x diesel (wife put gas in).. Anyway my dash lights, running lights and brake lights are not working. I checked fuses already and I did not see any obvious problems. I also replace the switch but that didn't work. Perhaps a ground somewhere or a relay? Turn signals and headlights work.
View 1 RepliesAll you need to do is pull out the head lite switch find the solid brown wire that is the running lights wire now find the yellow wire this is fog lights wire (these wires are on the gray plug ) you need a 3" piece of wire and 2 blue wire connectors it slips over the wires no cutting any wires then slide wire in the other end of the blue connector after you jump them your fog lights will come on with running lights and will not go off with high beams...
View 4 RepliesAny 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 RepliesJust bought a 2002 F-250 Crew Cab. It has the factory style running boards with the lights at each end. None of them where working so I changed the bulbs and still nothing. I decided to follow the wiring to make sure everything was good and found that neither one of the boards are plugged into anything. They both have about a 2' loomed harness with a plug on the end of each board and it is zipped tied to the frame. But there is no wiring nearby to plug it into, I have checked everywhere. I can run extra wiring no problem if I can find out where they are supposed to plug at.
View 14 RepliesGot my 02 f350 stuck in the mud a while back and had to get a deuce and a half to pull me out (F250 couldnt do it). Anyway since then my front parking/running lights don't work.
-I have checked the voltage at the bulb socket....nada
-I have of course checked the fuse and its fine (checked ALL fuses)
-ALL other running lights are working including top clearance lights, dually fender lights, etc.
I have an 05 f350. I cannot get trailer running lights to work. All other lights work. Trailer brakes work, battery charge for dump trailer. I've checked fuses under dash and under hood. Everything checks out. I'm Stumped.

No rear running lights or brake lights
No third brake lights
Headlights work
No signals or hazard.
I have power to the multifunction switch when I use a jumper wire to bypass the switch I can make the lights come on depending on which slot I put it in. I replaced the multifunction switch twice just to see if I got a new bad one the first time, but to no avail. I cant run my truck a night without the lights.
Looking for some info on wiring up some Day Lights Running Lights on a 2016 F250 with diesel engine? Thinking of adding LED lights to front of vehicle for day time use.
