Ford Wiring/Electrical :: 1978 F150 - Dash Lights Are Not Working
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.

Okay, my 1986 f150 with a 351w (non-feedback carbed) Has no lights on the cluster, and none of the gauges work (haven't tested the speedo yet, truck is not registered yet).
I also have a minor issue with the turn signals... Fronts work, no rears. The left turn indicator light on the dash does not come on but the right turn one does. All my "primary lights" (markers, tail, headlights) work fine. I have not yet tested the brake lights.
Fuses all look good, truck did have some roof leaks. I've done some research, does this sound like the dreaded voltage regulator issue for the gauges?
My assumption for the left turn indicator light is that there is a replaceable bulb in the dash (probably blown), is that right? Rear signals might be wiring (PO installed his own trailer wiring) or bulbs? haven't gotten that far into it yet...
Ford Wiring/Electrical :: 2003 F150 - Unconnected Wire In Firewall
Just bought a used, 03 F-150 SuperCrew Lariat. Having some minor electrical issues. While cleaning truck, I discovered a red wire coming into engine area on passenger side of vehicle. Wire has a built in 40amp fuse but isn't connected to anything. What this is for/ should be connected to???

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.

Are there any fuses or relays that I could look for besides what the owners manual calls out? Haynes manual is useless w/this problem also. Everything else seems to work fine. Haven't tried the AC or heat, but my gauges, pwr locks and mirrors are all fine. I'm stuck w/the windows down and no tunes.
View 3 RepliesFord 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.
View 3 RepliesFord 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.

I have been trying everything to get my speedo working on my Ford. It didn't work for 3 months after I got it then I decided to put some gear oil on the cable. This made it work for about 200 miles then it would only work with the clutch in and then not at all. I've replaced the speed sensor(not one on rear end the thing the cable goes into), and the gear that goes on the end of it. If I hook a drill up to the cable the tach moves. Could the cable be stretched or just needs some speedo cable lube?

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 :: PCM Randomly Shifting - 0.04V Dither?
m having a really difficult time with my '95 7.3. Basically, the PCM is randomly shifting the transmission out and back into 4th with the TC locked. When I say randomly, I mean very randomly: sometimes once in a 100 miles, other times chronically, with no relation to weather, temps, incline, driving conditions, etc.
According to FORScan (using a high quality ODBLink SX USB cable) some sensors are showing a 0.04V dither (this is with the engine off, van immobile): I've already replaced the PCM ($$$) to no avail.
I'm truly lost as to what to try next. I'm about ready to drive this thing into a canyon. FORScan screen shot showing 0.04V spikes
Ford Wiring/Electrical :: 1990 F150 - Center Brake Light Went Out
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?
Ford Wiring/Electrical :: 2008 F150 - Cold No Crank / No Start
I have an 08 F150 5.4L with about 68k miles. When the temperature is 40 degrees or colder it will not crank. I had the same issue with my 2005. I can turn the key and nothing, lights, radio and everything work. The dash display has dashes all the across for the miles, temp and compass. I have found out that it doesn't matter if I leave the key forward in the run position or try to crank, it won't do anything.
Battery is good and no problems with the truck. After the key is in and I give it anywhere from 15 to 60 seconds you can hear an electrical click real faintly and see the red security light come on and then the computer display comes on and then I can start with no problem? What could this be? My dealership has no clues and I can get it to act up because after I get it there it starts with no issue. The remotes work fine and this issue was why I got rid of my '05.

View 6 RepliesFord Wiring/Electrical :: 2012 F150 - Reverse Light Wire Color
I've searched all over and can't seem to find the answer. When I pull the tail light out of my 12 F150 there is a blue/wht wire and a black wire going to the back up light. I assume the blue wire is the positive and black is the ground. Is that correct?
