Question about 1992 Ford F250

1 Answer

Missing license plate wiring and complete assembly. How do I splice in to the trailer or tail lamp wiring? Off the "brown wire"? Is it really that easy?

I need a wiring diagram for a 1992 ford f-250 license plate light wiring diagrams. The entire unit is missing...not even "spare/left-over" connections or wires available behind/under bumper. There are only wires directly to the tail lamps and directly to the trailer socket.

These are the diagrams basically from the headlamp switch going back to the license plate lamps. The main splice after the headlamp switch going back is in the main harness near the warning chime module. If you need a larger picture or the entire outside lighting wiring, feel free to email me at csautomotivecars@att.net with all your vehicle information. Yes it is that simple by just splicing into the main rear light wiring at the brown wire. Hope this is what you were looking for.....

SOURCE: need to change rear bumper license plate bulbs in a 1991 F-250

push the light from inside your bumper to the outside. May have to tap with a hammer or wrench. New light will push in from the outside toward the inside. Reconnect the wire and you should be up and running!

SOURCE: tail light wiring connectors and wiring diagram

A test light checking each connector would be faster and easier to do. Maybe somebody may have a illustration for you but by far a simple test light is all you need with a helper turning on the different lights as you check them out and writing all your findings down

SOURCE: trailer wiring for 2005 Ford Escape without factory tow package

I had the sam problem with my '02 escape when I installed the hitch. I changed the turn signal relay under the dashboard on the drivers side of the dash with one from an escape that had a tow package(one was blue and the other was yellow...). worked fine for me after that. Don't know if it changed later...

Hello i have a toyota camry 1992 and my passenger side marker wont turn off ???


That's very odd, because the wiring for all of the side markers are just splices from the nearest park lamp wires- the rear tail light in the rear (and the license plate lamps are also splices from these tail lights), and in the front side markers, they are splices from the nearest park lamps. Do all the other park lights work and turn on with the park light switch on? I would examine the 2 wires from that side marker's socket to the wiring harness it goes into-the power wire would somewhere splice into the passenger tail light wire. The other wire would be a ground wire and also splices into a ground wire for the rear end. To be on, the marker lamp would have to be getting power from some live source. I can't imagine where. Does the rear passenger light work correctly?

In that harness to the rear where the park lamps run, there might be a live wire going to an electrical trunk latch switch, or maybe a trunk lamp. If the wires were frayed right beside the side marker wire, you could have some cross feeding of power between the two. Let me know, we always appreciate feedback.

Problem with the license plate lamp and the trailer connector.


It's possible these are two separate problems. You will have to find out why the power is not reaching the license plate lamp assembly, and this means tracing the circuit. Check for power and ground at the lamp. You will have to identify the correct wires and follow them back toward the fuse to find the problem. A wiring diagram will make it much easier to solve.
Same with the trailer connector. If it's not working, I assume you mean there is no power when you plug in your trailer. You will have to figure out which wire is supposed to supply battery voltage and why it isn't. Are there any broken wires? Corrosion? Does the trailer connector have any connection to the license plate lamps? (It shouldn't.)

Need instruction on fitting & wiring a towbar on my 1992 Mecedes 190E, 2ltr petrol Automatic


Hi there, the wiring sequence that I have is for the UK, I dont know where you are but I hope this helps
pin 1 Yellow L/H direction Indicator (turn Lamp)
pin 2 Blue Rear Fog Lamps
pin 3 White Earth Return
pin 4 Green R/H direction indicator (turn Lamp)
pin 5 Brown R/H Tail Lamp & No. Plate Lamp
pin 6 Red Stop Lamps
pin 7 Black L/H Tail Lamp & No. Plate lamp

you will have to trace the wires from the wiring loom and light clusters off the car to splice in the towbar wires which is quite easy, the chassis should have location points for the bracket, just make sure that the tow hitch is central and not obscuring the number/license plate..
Good Luck.

My brake lights work but the tail lights and license plate light don't work every time I turn on the fuse it blows I have a 1984 pontiac fiero.


Remove all bulbs on the tail lights and license plate circuit.
Replace fuse, turn on parking lamps- check if fuse blows without any lamps connected.
If it does, check for short circuit to ground on the taillight/license plate wiring.

If it doesn't blow, re-install one lamp at a time until all lights work. you may have a faulty lamp or lampsocket.

License plate lights do not work.


Sounds like you may have a wiring issue. I would cut the wires at the tag lamps, leaving enough to splice in new ones. Then pull one of your tail light assemblies out and, using a test light which is available from most parts stores for $5-10, figure out which wire is hot with the parking lights on. Splice a wire from there to your tag lamp socket. Then splice the other wire to the ground circuit at the tail lamp or find a good ground to wrap it around somewhere else (usually just about anything metal). Just find a bolt somewhere, back it out a bit and stick some of the stripped wire behind it at tighten it back up.

Need wire diagram to hook up trailer lights, truck not factory equipped w/harness,


I'm assuming you're just going to splice into the tail light wiring so that's what these wire colors are:
at the tail lamp 3 way connector:
black and yellow = park lamp
dark green and brown = left turn signal
there should be another connector with violet and black wire for reverse lights.
the stop lights are turned on through the turn signal circuits.

2001 Sportage Trailer wire connections


brown to the tail lights. yellow to left turn signal. green to right turn signal. this is a basic 3 wire hook-up i use all the time w/4wire connectors for all trailers. white wire is not used. ground is established when you hook to the ball.
to find the correct wire to splice to, use a testor (has a clip to the bare wire, and a sharp point to the truck frame). using a needle, push it through a wire to rear light harness. turn on the turn signal. check if the connection is the blinker, testing until you have the blinker wire. the tail lights can be attached to the license plate wire. brakes and blinkers use same wire, so brake lights will work whenever the turn signal is attached.
to be sure everything is working right, have a second person go inside the truck and work the signals, brakes and lights one at a time while you are at the back of the trailer telling what to do.
