Ford Wiring/Electrical :: 1988 F150 - Speedometer Not Working
I got my first truck today and it's a 1988 Ford F-150 and it runs great! The only issue is that the speedometer doesn't work and I won't be able to register it until it does. I was wondering what I can try out to maybe fix the issue and if not, how I would replace it. Every other gauge works, it's just the speedometer that isn't. The needle doesn't move at all it just sits at a 0 all the time.

Dash lights are not working in my 78 F150. The climate control lights come on and are dimable with the headlight switch. I pulled the cluster and the Blue/Red wire has voltage. Which might be the ground? The Seat belt light comes on at start and the left turn signal will blink. What am I missing. Oh the cluster is deteriorating. some of the bulb holes are chipping out.

I recently purchased a 1995 F150 4x4 with the 351 Windsor. Upon driving it I realized the speedo didn't work, transmission shifted hard,and OD light blinking. After googling my issue I found out it was the VSS. I climbed under the truck to find out the VSS isn't even plugged in. I searched for the wire but could not find it, only a spliced cable.....

Looking for a wiring diagram for a F-150 XLT LARIAT 5.8L 4BBL, all the books I have looked at show the wiring for this year with fuel injection and this truck came with a 351W with a Holley 600 4BBL, I have a few wire's in the engine compartment that melted away all the insulation, they are located close to where the harness passes the firewall before the ignition module. Is this a common problem on old models ?. Need a clear copy of the correct diagram for a f-150 1987 with carburetor, how I can get a copy so I can fix this problem before it gets worse.
View 3 RepliesFord Wiring/Electrical :: 2000 - Speedometer Works Over 40 MPH?
I have a 2000 Winnebago RV on a Ford F53 chassis. Recently, I turned the vehicle off and found that the speedometer was stuck at 40. After opening the dash in an attempt to investigate the instrument cluster, it dropped back to 0. However, upon moving the truck again, it jumps back to 40. Once I accelerate up to highway speeds, It begins to work properly above 40. Now it sounds just like every other broken cluster post I've seen, but here's where it becomes different:
When I stop somewhere, and its still at 40, I can flip the dash up and it immediately drops to 0 and stays normal until I move again. It then works until about 10, then shoots up to 40 again, and stays there until I hit 40, at which point it resumes working. Once I get below 40 again, it stays at 40 until I stop and flip the dash up.
I assume there must be a wire crossing that I am pulling apart by lifting the dash. However, there is a mess of wiring down there, and I don't have a clue how to find where it is crossing, assuming that's the problem.
Before the problem was discovered, I made three electrical changes, though I can't imagine why they would affect the speedo.
1. I rewired the trailer plug. I wasn't sure why, but I had no power coming to my running light wire in the towing harness. I couldn't figure out why that wire was dead, so I just tapped one of the tail lights and wired the trailer plug.
2. I replaced my backup camera. The old Sony began to flash, so I just ran the new camera wire under the frame and behind the dash. I wired the monitor to the existing cables that the old one was connected to.
3. The chassis battery somehow died while driving. It was slow to start in the morning when we left, and about seven hours later, I shut the vehicle down at a camping world and when I went to leave, nothing. Somehow the battery was down to 6 volts, which I have never seen before. Long story short, new battery and it started up and has been fine besides that speedometer thing.
Ford Wiring/Electrical :: 1991 F250 - Dash Lights Have Gone Out Entirely
I have a 1991 idi diesel f250. My dash lights have entirely gone out and i cannot seem to figure out why, i checked the fueses under the driver dash and under the hood for that matter and nothing is blown.
At the same time, the dome lights, door lights, cab lights, stereo, windows, ever the light in the ash trey etc, work perfectly fine. Could a wire have come loose behind the dash cluster and shorted out everything in the driver area?
I still get the high beam signal, check engine, engine, wait to start, and water in fuel light in the cluster. but no back lighting (when turning the key to the on position)...
Ford Wiring/Electrical :: 1995 F150 - Headlights Not Turning On
Here's the breakdown. I have a '95 Ford F150 that I bought the previous year and it has been nothing but a problem. The most recent problem is the attempt to turn on the headlights. I will pull the plunger to turn on the headlights but I will only get the parking lights and when attempting to turn on the high beams I still get nothing. The only way that I get any sort of lighting is if I pull on the turning stick (almost like doing a manual override on a tripped wall plugin). Now here's the kicker. I still have parking lights, brake, tail, cab, and dash lights. Winter in quickly approaching and the nights are already getting dark, pretty soon the days will be just as dark.

I have a 1999 Ford F150 6 cyl. 4.2, 2 WD with 160,000 miles. Replaced the battery May 2010.
Today battery light came on. Battery gauge did not look like it was discharging. Had battery checked they said it was a little low but OK. Then they continued test and tried to check alternator, test stopped and they said something wrong with alternator most likely.
I took alternator out and had it bench tested. They said it was OK, putting out 98 amp on 95 amp alternator. They said check wires, grounds, harness, connections. Checked connections and wires as much as possible, reinstalled alternator, light still on.
Have not checked fuses yet. Was told to start vehicle, disconnect positive battery cable and if engine continued to run alternator was good, if cut off alternator was bad and to replace. Should I try this and is it true?
What is the part on the fire wall that is between the alternator and the battery that the wire connection runs through? Can it be bench tested/checked?
Ford Wiring/Electrical :: 7 Pin Trailer Wiring - Running Lights Not Working
Just bought an 04 Super duty with the factory plug 7pin and 4 pin plug. Checked the fuses and finally tracked down the 2 relays under the hood but can't seem to find anything wrong. Everything on the trailer works except for the running lights. Is there another fuse or something I have missed? Trailer works fine on my buddies Duramax and worked fine on my old 97.

My center brake light went out a month ago. Thought it was the bulb so replaced that, still didn't work. Checked the fuse and its not broken so my guess was electrical?
Hasn't come on once that I know of but I was randomly walking behind my truck and the light was on. Truck was off lights were off and key wasn't in the ignition.
Went and turned my truck on and turned the lights on and the cbl stayed on. When I switched my lights off it went out and stayed out.
Now I'm definitely thinking wiring but not sure where to start fixing?
Oh and it's a 1990 F150 XLT

Ford Wiring/Electrical :: 2001 F150 - Stalling Out During Idle Like Not Getting Enough Fuel
I have an 01' f150 that everything is going out on. I've replaced the GEM module thinking that's what it was to no avail. First thing to go was all four windows which have currently been stuck halfway down for 2 weeks. It's stalling out during idle like it isn't getting enough fuel to it. Brake and engine light on dash are staying on. Radio, interior lights won't come on. Will not come out of park once in. I have to do the old forward, back, middle key trick to get it out of park into neutral so I can start it and go. I've also checked all fuses and relays under dash and under Hood.

My 85 f150 5L is parked to far in into my alley.. the last time i saw my keys i moved it up to water the plants that it was tucked almost on top of.
ive been looking for the keys for 2 months.. the truck isnt being driven at all but i think my neighbors are getting mad at it being out so far.
I can get in the engine bay, and i have jumped the starter on our big trucks at work before.. but what wires do i have to join to put the ignition into the run position?
