E-150, 5.8/351
The Haynes manual says not to disconnect battery (for whatever amount of time) to clear codes because it also clears the keep alive memory forcing the computer to relearn.
What is the correct way to clear codes? The manual says talks about jumping the OBD connectors some way but I cannot tell what is showing in the picture.
I just tried doing the self test for reading the codes via the check engine light with the OBD1 system on my '93 4.0 Ranger. Problem is: When trying to mark down the flashes of the check engine light, they flash so erratically and rapidly that there is no way to accurately count. At times the light flickers so fast it never even gets to get fully bright enough to tell if it is actually a "flash" or not. I'm (again) trying to diagnose an issue with the truck starting and running fine for about 3-4 minutes and then like flipping a switch begins blubbering and belching out black smoke, check engine light flashes on/off randomly, then the engine will eventually die. It will restart provided the ignition switch is turned all the way off and attempted again, generating same results only within 30 seconds or so. If you try restarting w/o turning the ignition all the way off, it'll spin over but won't start. ECM?
View 4 RepliesI am a beginner when it comes to anything involving wiring. I am looking to re-wire all of the wiring coming off of the instrument cluster gauges. Once I have completed all of the wiring on the gauges, I may feel confident to move onto something else. As of rite now, it appears as though my truck is still running on all of the original wiring, and over the past few weeks, I have been having many wiring related issues. I found a schematic that includes the wiring for the gauges that I am going to go off of. I have a couple of questions before I begin.
1.) On the schematic, it shows connectors such as "Connector G" which is moving all of the gauges wires to there locations. Do I need to use a specific Ford connector, or could I purchase a new connector at any hardware store that carries them? As far as I am concerned, connectors do the same thing as all other connectors. (Let you connect and disconnect for easy instrument cluster removal.)
2.) I am not looking to purchase one of those expensive wiring harnesses. I would like to just purchase some wire that I can cut / use myself. What brand / type of wire should I be looking to purchase? I do not care if it is striped / colored as I will use wire tabs to name / label each wire.
Other than that, I feel confident enough to attempt something such as this. Here is the wiring schematic I am going to use.....
Any COMPLETE headlight switch wiring diagram? Everything I find online only shows 2-3 wires in each sub connector, nothing with all wires and colors, and what they do. and of course the factory service manuals no longer work on my new computer. the switch and associated wires went up in smoke 2 hours ago, and this truck is my only means of transportation rite now. what i need is headlight wiring with colors so i can temporary hook up a toggle switch to have lights until the new switch and connectors come in next week. I went to pull the switch and connectors out of the parts truck, but of course that does not have fog lights so it uses different switch and connections.
View 14 RepliesI plan on moving the engine/drivetrain from my 1986 F350 460 to my 1996 F250. I also want to move over the 1986's ignition system with a Duraspark 2 setup.
Although I could just cut in the easiest places to remove the wiring for later reuse I am looking for where to make the cuts, what to take and what to scrap. Alternatively I am also asking if there are aftermarket or OEM replacement sets out there are aren't a ton of money. The current harness in the 1986 has been sprayed with engine oil and cooked for 27 years so I am looking at alternative options if there are any.
I have a 97 F250 HD. Wiring the rear tail lights. When we bought it the had cut off the wires going to both sides of the rear lighting assemblys and I was wondering what wire went to what i have the left turn signal working just can't seem to get the brake/back up light to work on that side and i can't figure out how to get the right side going either.
View 8 RepliesLooking for a source for a wiring diagram for the 2003/4 f350 instrument cluster, specifically the wiring/connectors to the gauges? A link to a PDF file would be nice. I would like to try and disconnect the PCM control to the transmission temperature and engine temperature and drive the gauges from my own sensors to bypass the non-linear behavior that ford decided was in our best interest. I am NOT interested in installing any more gauges, just want to control the ones already present with my own signals. It is possible that these gauges are all addressable devices on a common bus, instead of individual controls.
View 8 RepliesJust 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.
View 14 RepliesIm installing a set of 04 lariat seats into a 00 truck. I need to know how to hook up the heat. The power part is no problem. What I thought was right which was a separate constant 12v and a switched 12v for the module and ground apparently isnt right. If somebody could ohm out their harness on a 01 truck that would be great. As I have it right now the light on the switch comes on but almost instantly turns off.
View 14 RepliesLooking 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 RepliesLet me start by saying electrical is something I really have no knowledge of....(never used any kind of an elec meter and don't have one) simple, Pos-grd and fuse, NP. I really don't want to fry something in these expensive new seats w/my normal trial and mostly ERROR!
The 08 (drivers) seat has 4 wires in the input clip.
GRN-RED (heavy gauge)
BLK-PURP (heavy gauge
BLU-RED
BLK-WHT
and my 01 whip out of the floor has a 3 wire setup.
GRN (heavy gauge)
BLK (heavy gauge)
BRN-BLU
I can wire PS side seat from fuse box and ground it NP. It only has a 2 wire set-up in the new seat.
I am curious if it is possible to make a stand alone controller for the electric shift transfer case in a 2000 F-350?
The reason I ask is, this is swapped into a 4x4 conversion in a van and I would like the transfer case to work like the factory, but I don't want to swap over the whole GEM module. I have the high to low and low to high shift relays and wiring, the selector switch from the dash.
I know that powering up the relays will shift the transfer case, but the GEM module tells when the relays need to shut off, and that is where I am not sure what to do. I am assuming that the other plug on the shift motor (6 pin plug) is the sensor that tells the GEM module where the shift is at.
What needs to be done (with a bank of relays).....
Need a wire diagram. I have a connector in the cab that has red,blue,lt green,white wires. It's causing my brake lights not to work. I need a wire diagram that shows were they go. I can't find these wires in my Haynes manual.

View 1 RepliesWhere can I find/buy a wiring schematic for a 2012 Ford E350 with the 5.4 L V8?
View 1 RepliesI just bought a hard to start 1990 F250. Per the board, just replaced all 8 glow plugs with Motorcraft. Still wouldn't start (it turns over but will only start if you use either). I attempted to install a new BWD brand (Borg Warner I believe) glow plug connector relay today...I removed the old no problem, but am unsure what wires to plug where....the only connection that I'm sure about is the blue wire that works the WTS feature...it plugs in easily but I don't know if there are other connections that need to be made or not? All the wires run from the posts and into the bottom of the unit.
View 2 RepliesSo I'm writing this for my friend but he has a 1978 F-150 with a 1969 390 in it. He recently had a problem where his starter got stuck and it lit the wires connected to the solenoid up in flames. Well anyways we replaced all the wires that were attached to the solenoid and replaced the solenoid and the starter also. But after wiring it up it has no power whatsoever. The battery is also brand new and the fuse links are fine. What is causing this?
View 2 RepliesMy 1999 Ford Ranger XLT, 6 cylinder, auto trans, with 134K miles has an electric problem. When I turn the key to the 'on' position, all dash lights show normal, headlights work, radio plays, etc. But when I turn the key to the 'start' position, all electric power is lost. The power remains lost until I disconnect and reconnect the battery ground wire. After reconnecting, I again have power until the key is turned to the 'start' position. I was able to jump start the truck, so I assumed I needed a new battery. I bought one a week ago, and was back to normal until today. The truck started, I drove 4 miles to the grocery store, and then I found myself back to square 1 (i.e., the no-start situation).
