Question about 1988 Ford F 250

Open Question

Need wiring diagram for 88 ford f 250 tach and voltmeter.

Need wiring diagram for 88 f 250 showing tachometer circuit from inst panel, all the way to distributor and coil. i took the 351w out, out in carburated 460. electronic dist and brainbox are out of 83 f 250. part #on brain is D6AE 12A199. # on dist is C8VF 1213-8orB. the coil i just bought at napa for 83 f 250 indicates no external resistor needed. other coils say on them to use with resistor, this one does not. so i assume this electonic ign syswill not need an added in resistor. so i may need a diagram for the 83 f 250 460 elec ign sys dist and control box.

SOURCE: i need a wiring diagram for an 83 crown victoria starter coil

if you turn the key and the engine spins but doesnt fire try checking the timing for it to make spark at the time you need it to ,if it's out it wont catch and run or check for spark at the spark plug make sure it has spark use a dummy sparkplug in the boot and hold it on a ground and crank engine look for a blueish spark and if you have bare hands holding it you'll get a good jolt (insulated pliers)

SOURCE: f 250 ford

Before you replace the ECU check to see that the fuel pump relay is working. It will be on the drivers side under the hood located just above the fenderwell. It should be mounted on a plastic piece with two other relays beside it. This relay is only about $ 16.00.

SOURCE: negative wire on coil to hook up tach on 1995

If you have a good look at the coil, it should still have a positive and negative sign on it somewhere. Try not let the extra wires confuse you too much. These are for the ignition module in the distributor. let me know if you need further clarification after you've had a look.

Firing order for 1982 351w in f150 truck


If it's a California truck it's a good chance the ignition is EEC-III (brown grommet on ignition module.)

The EEC-III distributor rotor fires alternately from both sides of the distributor rotor.

The the spark plug wires for an EEC-III distributor will be wired counter clock-wise in a different order.

1975 351W with 2 bbl carb, runs great for about 10 minutes, then dies.


Chances are it is the ignition box on the fender. It controls the ground signal to the coil and the timing.
If you can duplicate the problem and get it to "not start" you could test the box. Otherwise it may be tough to troubleshoot.
There's a chance something is going on with the pickup coil in the distributor too.

Need hei distributor wiring diagram


That distributor is an easy one. You need to connect the harness attached to the distributor housing to the cap. There is a marking on the cap that says "Batt" Connect that to the hot lead from the ignition switch that is on (with 12V present) and off with switch off. Likely the connector and wire are still in the engine compartment somewhere near the distributor. The other lead connection is marked "tach" you don't need to connect it anywhere but can attach a hand held or on dash tachometer to it.
If you get no spark from the distributor, either the module inside it is bad (no test for that. they are either good or bad) or one of the wires coming from the pickup coil that attach to the module has broken (common on those). (assuming good or new cap, rotor and coil).
It's a very simple and reliable distributor. In fact I'm using one on a 305 Monte Carlo racemobile right now. (with MSD coil, cap and rotor)!!!

Need to know how to hook up a tachometer with a shift light on it there are four wires


The Black wire will connect to body ground, and it should be a good solid ground and if this wire is not grounded well then you might receive a primary voltage shock if you touch anything that is metal or grounded inside of the vehicle when the engine is running.

The Red wire should be connected to power when the key is in the "Run" position only, and a good place to find that source is one of the "IGN" connections at the fuse panel using a covered female spade connector. Use a test light and be certain that the connection only has power when the key is in the "Run" position, and has no power when the key is in the "Off" or "Accy" position.

The White or Yellow wire should connect to the "LPS" connection at the fuse panel next to the LPS fuse using a covered female spade connector.

The Green wire will connect to the "-" negative side of the ignition coil or the primary side of the ignition coil, and for later model GM HEI equipped vehicles this will be the "Tach" connection next to the main "Bat" connection on the distributor cap if the ignition coil is mounted inside of the distributor cap, or to the "Tach" or "Test" lead that runs from the negative side of the ignition coil if the ignition coil is mounted separate from the distributor. To locate the lead run down the wire from the negative side of the ignition coil and the lead should break off from that wire and it should have a tag on the wire that will say either "Tach" or "Test" (sometimes it is just an empty black wire connector) and that is if the lead does not come straight off from the wire connector at the ignition coil. If there is no lead you can get a wire tap connector to tap into the wire from the negative side of the ignition coil and then use a covered male spade connector to connect the Green wire from the tachometer to the wire tap connector.

Here is a diagram to help assist you although it might be hard to make it out, and let me know if you require any further assistance.

Took the efi 5.0 out my 89 bronco and installed a 351w carburated out a 84 bronco.wiring in the 84 was screwed.replaced the distributor with a points distributor and coil and no matter how i wire it it...


I dont know what "points distributor" you installed or how you made sure you installed it correctly. But a more simple way would be to get a distributor that has the coil pack built in. That kind only would require 2 wire connection. Positive 12 v and ground. also it has a 3rd connection you may use that is for the tac. very simple.
The one you have now ... do you get spark to the spark plugs. If so I would fool around more with being sure it is installed correctly, find TDC and be sure the rotor is pointing to the #1 cylinder, ALSO that you have the plug wires going in the right order on the cap. I dont think you will have luck with the computer compatible question.
