My dumb self cut my factory harness to install a radio and after hooking up said radio (which I know how to do) it popped a fuse. So to avoid any trouble I need to put another harness in but again with my stupidity I cut the wires too short. finding the correct harness
View 2 RepliesSo after hitting a pothole, it would seem like half the engine lost power, after some searching around, i found that i would most likely be the harness inside the valve cover that has lost connection.
Its the right side, so i would need to take of the turbo pipe, and probably something else to get to it.
Since i'm doing this job, what to check out along the way? I want my 7.3 to be as reliable as possible.
I will probably ask some questions along the way, it can be a challenge sometimes to own a car that not many mechanics are familiar with, but as i have read online, this should be a very straight forward fix.
Can the harness be upgraded so it doesn't happen again? Its an 02
While engine was running. brake switch "recall harness" shorted to exhaust manifold blowing fuse 22. truck died instantly. found the short and replaced fuse. checked all fuses good but no start since. WTS indicator stays on. tried a new GPR and a new CPS.
Does IPR and brake switch (on master cylinder) share fuse 22? fuse 22 holds now (when wire was fused to exhaust manifold it blew as soon as key turned on). unplugged FBH no change. recall harness "beeps" good and wires do not appear burnt. also shuffled relays around in central junction box.
Could formerly access OBD2 port with superchips programmer but no access now. fearing the worst, but hoping maybe bad ipr sensor (or another sensor) could cause this. Is it likely or not that this short fried the PCM?
I am going to add some led's to illuminate the steps getting into my truck at night. I plan on putting them directly under the door over the steps. Is there a wire under the door threshold I can tap into at each door? If so what color? If not, where to get the power from. I want them to turn on and off with the interior lights when doors are opened.
View 1 RepliesAs part of my ongoing P1393 troubleshooting, I’ve found that I can’t get the main engine wire harness separated. The big connector by the driver’s side valve cover.
I’ve cranked and cranked in the correct direction, but the plug never separates. I tried a cordless impact wrench and it still doesn’t move. (Edit -- the bolt moves very freely, but it doesn't push out one side (e.g. like removing the PCM) I can't figure out how to separate the two sides.)
Any tips on how to get it separated? Can I cut off the bolt head to get it separated?
Where I can get the head light to fog light wiring harness..it is almost as hard as finding the holly grail..... 2001 f350 7.3 .......
View 9 RepliesI have what might be a big problem, the main harness on top of the drivers side valve cover I can't get undone, the bolt holding it together is stripped or the nut who knows? wondering if there is any way to take it apart otherwise.

I'm trying to find a part number for the wiring harness that sits on top of the motor and plugs into the valve cover gaskets. The previous owner replaced the pigtails but the wires were cut so far back that there is virtually nothing left coming out of the harness. What the actual harness looks like other than it has the 9 pin plug on it or whether both sides require an individual harness. What is the part number or picture of said harness. Just in case.... it's a 2001 7.3.
View 14 RepliesI have a 2000 Ford F550 7.3. I bought a Superchips programmer to read the codes on my truck and up pops this P1316, so I did some research and found out that the most common problem is the injector wiring harness. I bought new valve cover gaskets and the injector wiring as well because the truck is old and I figured new wires wouldn't hurt.
So after installing the new wiring harness and gaskets I'm still getting this Code! The truck idles rough and serge's sometimes, also there is a lack of power and some shaking between 40 and 50 miles per hour, however form 50 to 60 MPH seem's to be just fine. I don't trust the "Mechanic Shops" around here and will only take the truck in as a last resort.
Had to change the UVC harness on my 2001 7.3. Truck fell out. Trailered it home and changed the UVC harness on the passenger side. Truck is running great, but now the OD light is flashing. Can't read transmission codes, but was wondering if something from the bad harness could have caused this? Any thoughts?
View 7 RepliesMy factory radio will not work. The person who had the truck before me installed an after market radio and it works fine, but the factory radio will not power up when I plug it in...is the radio shot or is there a way to fix it.
View 1 RepliesI have a 95 f-250 psd with factory remote keyless entry. about 3 weeks ago i had a fuse blow that powers the keyless entry module, speed control, and a number of other systems.
If I replaced the fuse it blew right away so i got my wiring diagrams out and started unplugging parts of the circuit and my last attempt was to unplug the keyless entry module. presto no blown fuse so i got a module from a junk yard fixed the problem and now it has happened again. same exact thing. unhook the module and no blown fuse. i took the first module apart and saw no burned parts and no visible damage but here i am blowing fuses with no door locks, dome light and a few other things.
The fuse that blows is fuse 8. I am a mechanic and have full access to anything I need. I have another module under warantee but I want to be sure that its not something other than the module causing problems.
How can I eliminate the factory Ford (2001 7.3) quick connect fuel line clamp on the output side on my OEM fuel pump? Do I just cut off the factory quick connect and add some 5/15 fuel line? Is it that simple or is there something I need to know prior to cutting off the factory quick connect clamps?
View 6 RepliesI'm still fighting tow harness problems on my '01 F 250. I started by replacing the 7-way pig tail with a new one which didn't work. Then I undid all the butchering of the harness that was done previously. The factory harness had scotch locks all over it that were used to splice in a 6-way and a 7-way into the bed. I liquid taped all the nicks in the wires. Then I checked for power at the factory harness end where the pigtail plugs in. I have park/running lights, and one of the ports flashes for the left turn signal/flashers/stop lamps. I got rained on before I could check further up the wire. If I have no power to the wire further up is there another place to check?
View 2 RepliesIs it possible to add the factory keyless entry without replacing the complete dash harness? I have an aftermarket unit I can add but I'd rather have oe if possible. Truck is an 2003 f250 v10.
View 1 RepliesI now have a 2002, 7.3, 250, 4x4 and love it. Everything but the milege. All in all it's a great ride. I have one little problem that's driven me nuts.
The power windows and the radio go out occasionally. Both at the same time. They come back on...... sometimes. Sometimes it takes a day or two. I've checked the fuses and then saw that there is a breaker in the 601 location in the fuse box that's probably causing the problem.
But I thought that it was supposed to shut off to protect that circuit when there is a short somewhere. I don't know where to go or how to locate the short if in fact this is my problem.
On my 2003 powersteering the windows and radio will just quit working. Then they will come on again. Maybe in and hour or a day or a week. Where do I sart.
View 6 RepliesMy buddy is selling his truck in a couple days and was taking out speakers, afe intake, and satelite radio. I go to start the truck and i have no power to windows, no power to radio and no domelight when i switch it on and off. Dont know what i did but none of this works and everything else does.
I checked all fused all were good. I searched the forum for a solution and they said something about the automatic delay relay and i bought a new one and nothing still. I am not sure what else to do i checked with voltmeter if i had anypower to the window or radio and nothing. But the radios clock works and when i turn on the light it illuminates but doesnt turn on.
The truck is a 2002 7.3L Crewcab. f350
The short story is I sent my chip to dp tuner last week while on vacation to have Jody update my programs. The ecu was out of the truck for about a week. I reinstalled everything today. Everything works fine except my radio won't turn on. Clock only comes on when headlights are on. Checked all the fuses all good except #32 which is a 5a. Manual says it's the radio start fuse. Fuse is fine not blown out, new one installed still no power on either side of the fuse. Where should I look now. 2002 super duty
View 5 RepliesGot a 2003 6.0 that seems to be leaking from the glow plug harness. How hard would it be to just replace them? I've heard that trying to remove these things can be a pain because they almost always break. But if I'm just going to replace them who cares right?
Is there anything I need to be careful about? Or can I just rip em on out? Also I've noticed two different styles of harness should I replace mine with the other style or just keep it the same? And yes those valve cover nuts are loose. I'm aware
