Well...apparently I'm not alone on this issue. I've searched numerous other forums, where Ford owners are experiencing this very same issue. This is the only one that provides any amount of insight to the problem.

I've got a 2000 F150, with the 7 - 4 barrel plug connection. I just bought a small ATV trailer. I've got signals and brake lights, but no marker lights. I see that several of you folks have recommended to check fuse #38 near the kick panel. Apparently that must only apply to the F250 and up models? My panel only has 31 fuse locations, and 5 relays....which are all good. The power dist box under the hood has several fuse/relay locations that appear to be relevant, and they are all good as well.

I've checked the plug outlet, and checked the wiring back as far as I could with a test light, and got nothing on the brown wire (for marker lts). At that point I gave up.

Looks like I may have to do some re-wiring.

Please note that this discussion was related to the 04 and newer Super-duty trucks. Your older vehicle is completely different after the model change-over for 2004.

I'll post a link to your relevant schematic shortly, I need to move to a different computer.

Edit: Here you go: http://www.mediafire.com/?3n2yzydm1c9 See sheet 95-3

Verify the running lamp relay energizes when the headlights are turned ON ( light toush will allow you to feel it click). Check fuse F5 in the under-hood box, it supplies lamp power for the trailer marker/running and backup lamps.

There is another thread on this subject. It seems that on the 250 anyway, that there is a relay built into the fuse panel, and is not repairable. A new panel is required. Someone posted, how to wire in a new relay on the outside and wire around the failed one. I did it and it worked for me. You will need to start at the fuse that controls your hitch running lights and go from there. A search on the problem should bring it up. I too am new to the forum,and don't know how to find it, but there is a lot of nice people on here that are willing to help.

2000 F250. This year does have a serviceable relay for the trailer running light circuit. It's in a "instrument panel relay block". All they say is it's behind the instrument panel as far as location.

In 2000 you have a fuse #4, 20 amp in the underhood fuse box. This fuse feeds the reverse relay and the trailer running light relay. After it passes through these relays, it heads on back to the plug.

7 pin trailer wiring help

PADIRT I am having the same problem with my '99 F350 supercab. The turn signals & brake lights work but no running lights or tail lights. Not a problem if I only drive during the daytime But I still have to find the problem.

[quote=Maxium4x4;5878313]THE TRAILER LAMPS ARE INOPERATIVE — TRAILER PARKING LAMPS


Maxium4x4 would you happen to have the drawing on the 7 pin plug and what connector is for what for a 2009 F250? ..

Apparently I'm having problem with my center pin .. My understanding it's the 12v supply..
What I am trying to do is run that to a battery located in the trailer to keep it charged. When I connect the wire to the battery in the trailer my trucks backup lights come on.

Seems that there is a wire mismatch going from trailer to truck's backup lights....

I had that same problem ...
My issue was a bad ground wire to the clearance lights were not making a good connection ..
You may want to make up a small jumper wire and use it as a temporary ground just to see if one of your clearance lights light up with your headlights on and someone outside the trailer .....

Parking lamps

03 Excursion with trailer package- parking lamps stayed on all the time. Stayed on when switch was taken out and when security module was taken out. Someone unhooked the wire from the tail lights to the trailer plug- the lights wouldn't turn off. Constantly on. Customer didn't do it, so we have no clue. Pull fuse 38 and the lights would shut off but than the trailer lights wouldn't work. Thought it was the parking relay, which of course is NON serviceable so you would have to get a new fuse box (complete) or run a new relay. We ran the new relay and it still had the problem, of course until we saw the brown wire in the back of the truck running from the tail lights to the trailer plug....

Very frustrating, but it works now like it should!!!

Just thought I would add to this old thread because it did help us look into this problem. And I have no clue who or why the wire was ran...so you never know if someone else does the same thing now knowing what it will cause!!!

What truck? Is this a 6 pin or a 7 pin plug? If it's the brake wire, no. Are you using a 7 pin to 6 pin adapter?
