Does anyone have wiring diagrams, from the back of the coil to all sensors, also including the grounds to the block behind the oil dipstick? Thanks

Ok currently watching the super bowl at my son's. But I can look them up for you when I get home.
What year, engine and trans?

Thanks 1995, aw4, 4.0

All the grounds you will ever need!

 

[TgRamsey]

Yep that's it thanks

 

[Gluckmysock]

Sure Happy to help.

Gluck I need your help, here's the quick deal. My buddy bought a white 95, just like mine. Someone has performed electronic surgery, and it's definitely malpractice, lol. I have regrounded it, that was fun. I have to figure out the electric fan relay, cause the damn thing runs as soon as you turn the ignition. Gauges don't work, but the main thing that is distressing me, is they have wired the coil straight to the battery. Like cut open the plastic wire pack, fished out a hot and ran it straight to the battery, I'm guessing the other is grounded on the bottom of the coil on the frame, cause this thing runs, and not too bad. Where does that hot tie back into the wiring harness, I would think behind the alternator, haven't really dug dug in. I'm trying to get it 5 miles to my house so I can tear into it better.

You diagram has been helpful, but without pics I just can't really figure some things out. I understand them, but when the whole group of wires are loose and hanging there I'm a bit overwhelmed and confused

 

[TgRamsey]

For example the one wire runs to the generator i.e alternator? And if anyone has any pics of connections or how that connects it would be priceless to me

 

[Gluckmysock]

I'm at work, but I can certainly get you that info when I get home.
The wires are all color coded and listed on the diagram. The generator, or yes alternator is circuit A142. 18DG OR is the wire size (18 gauge, yeah they are small) DG is for Dark Green and OR is for Orange which is a tracer. Or a line along the length of the wire in that color. Anything with a C# is a connector. Anything with an S# is a splice and anything with a G# is a ground. Numbers in parenthesis is the pin # of that component or connector. Hope this helps for now.

 

[Gluckmysock]

See if these help.

and this one.

Ok, I've torn this down. Maybe you can explain it to me. Ok the bundle of wires that come out of the big fuse box and runs to the coil, alt, etc. Ok.. on the coil, it has a green and a black, the black has been spliced to run to the coil plug. Ok behind the alt, there is another green wire that is spliced and hot wired to the battery post. Shouldn't the green wires be united at the coil plug, but where does this black wire go? Or does the green wire go elsewhere. The spliced green wire is in that bundle right behind the alt. I just dont know why that green wire is spliced and ran to the battery, and it's not the green coming from the fuse box, ugh!!! I meant to include pics. It runs, dont get me wrong. But it looks cobbled up.

 

[TgRamsey]

All this rambling, I have wire that I cannot find its home. I'd look at mine, but mine is still all taped,protected, and purdy. This is driving me crazy

 

[Gluckmysock]

I think they cut the green wire because it comes from the auto shutdown relay, which it what sends it power. Since that circuit is faulty, they cut it and bypassed it to get power to the coil and alternator. The black wire from the coil should go to the computer

 

[TgRamsey]

Ok shouldn't there be a fuse link between the 3 green wires, I think there is suppose to be a fuse link or 3 splice there. I think the green wire they cut, runs the ecm, cause we have lights, no control panel readings, no rpm, no gas, no temp, no voltage. I'm going to send pics I'm not vocalizing very well

 

[Gluckmysock]

Look at the last wiring diagram I posted above. it shows a wire from the "generator" AKA alternator, to 2 fuses prior to going to the battery. the wire shows 8 gauge so I don't think this one has a fusible link.
I have attached the wiring for a 96 FOR CLARIFACATION purposes only. I am not yelling, I just don't want someone scrolling to the end and think this is in a 95.

1st pic the wiring bundle coming from the alt, one green is to the coil, the other green goes back to the batt, I suppose to recharge.
3rd pic is coming from the fuse box, black and green orange is going to the coil, this runs from the fender, hence like the other pic that shows the wiring bundle it comes from, it includes the oil sensor wire, alt power, blue alt wire that plugs in, and that blk and green that goes to the coil plug, the green and orange that comes out of the alt bundle is my problem, where does it go, last pic

 

[Gluckmysock]

Look at the wiring diagram in post 9 it shows a DG/OR split 3 ways. 1 wire going to the Auto shutdown relay, 1 wire to the coil and 1 to the alt. All dark green with an orange tracer. the mystery wire goes to the fuse box (Power distribution center) and connects to the Auto shutdown relay. I'm guessing that something happened to the ASD circuit and they bypassed it by connecting that wire to battery power.
