Ford Wiring/Electrical :: 1985 - After TPS Sensor 0 Volts?
Oct 16, 2013
I have an 85 bronco ii 2.8l, carb, with around 109K on it , ran pretty good, some stubles here and there but found out how to read codes and went from there.... Retreived codes 23, 31 and 84. Checked TPS, had voltage to sig return pin but was low, pulled the carb, bought a rebuild kit while i was at it and redid most of the gaskets but did not take the inner parts of the carb out, put on a new TPS, installed the carb, unhooked battery for about half an hour and noticed it idled very high. Once you were moving the rpm's would drop but at idle would climb again. I ran the codes again and got 31, 63 and 84. checked volts from black to vref i have 4.9 and from black to sigrtn i have 0. i have traced all 3 wires through the bundle and did not see any breaks i know that the green wire goes to the ECM? but i do not know what to check from this point.

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?

85 ford ranger 2.3 efi .. My brake lights still aren't coming on. According to the Haynes manual, the wire that runs from the stop light fuse goes from there to the hazard flasher and then to the brake light switch. Since I have checked everything else, is it possible that the hazards are causing a break in the connection?

Where is the cruise control amplifier located on an 85 F-150? The Chilton manual just says "behind the instrument panel". No pic or further description. Just looking up from the bottom of the dash I see a "black box" with 2 wires going into the top of it located just between the steering column and the wiper switch.
Is this it?

85 f150. My driver side brake light and turn signal in the back quit working. The tail light works tho which is a different filament. The bulb is good and I changed the flasher relay...the circle thing in the fuse panel. Everything else works just fine. looking for a starting point.

My truck just came out of the shop. Was in for spark plug change. My parking sensor button is lighted up with OFF. I tried pressing it but it stays in OFF and no beeping occurring when in reverse and there are objects behind me. What could it be? Fuse?

Having a chance to try an O2 Sensor Simulator on your truck? I am wondering if they actualy work or if I should just stay away from them. Are there any problems or improvements using a SIM?

I have a idle problem that happens on and off. with my 89 f250 351, it revs at 1900 rpm and when I unplug the vacuum hose to the map sensor it idles about 700 rpm. I've already replaced the map sensor and it does the same thing. i cant find any vacuum leaks anywhere and when i unplug the connector to the IAC nothing happens it continues to rev high.

SO, my Buick has given the code for bad TPS, and it was replaced a little over a year ago...and now after the same symptoms, replaced again.. However, this time, right after replacing, it gave the code again, and still stalls out /doesn't want to stay running especially when put in gear. My regular mechanic also recently just put on a new catalytic converter and a new fuel pump and fuel filter. I'm at a loss, and desperately need my car back.
A little back history...about 3 years ago a 'friend' was to work on my car to install the thermostat and power washed the engine...which shortly after started having all kinds of electrical issues. Right after that, my mechanic had to install a coil, spark plugs, new ignition panel and the 1st tps.

I 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.

I 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.

Looking 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.

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.

Im 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.

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.

Let 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).....
