ok, yes i have the wiring schematics from the FSM. I have the entire S4\S5 schematic on my comp in fact. That's not what i'm looking for.

I'm wondering if by some chance someone here has seen a website or something, with the definition of each plug's wire for the S4 FC. What I mean is like this. For example, there's 3 wires going to the headlight. One for high beam, one low beam, and one ground. I'm trying to find an actual definition like so:

Headlight harness plug:
R/B = low beam
R/W = high beam
B = ground


.....and so on for each plug of the harness

I'm going through rewiring my entire car with a new aftermarket harness. Trying to reverse engineer this FSM's wiring schematic is hell.

anyone know?

i thought the FSM had all that. read up in the FSM or google on how to read wiring diagrams and it will help alot.

ahyc84

see, i did do that. I know how to read a wiring diagram. It's just reverse engineering that's giving me a headache.

the FSM shows it all yes, but on a single plug, you might have to look through 3 pages to find all the systems

i won't die with out it. I just thought i'd ask to see if there might be such a thing out there. If there is, it'd save me a lot of time. I'm trying to do this while being full time at school. So any time saved would be great

No, you don't.
If you really knew how, you wouldn't be asking such trivial questions.

Those are the wire colours, just like you'll see on any wiring diagram... The wire colour chart is at the front of the chapter.

I cannot imagine a bigger waste of time and money. Most of the wiring in the car will be absolutely fine. The only wiring that might ever need to be replaced is stuff exposed to the elements or engine bay heat. Why are you doing this?

ahyc84

ok. I'm NOT asking for the color definition.

I'm talkin about what each wire in each plug does.

The FSM DOES NOT show clearly on everything. On a single plug, you have to jump through possibly a few other chapter of other systems to figur it out.

reted, figur out what the question really is before getting hostile with insults. It just makes you a douche when you write something without knowing the actual situation.

EXAMPLE

http://i97.photobucket.com/albums/l2...turnsignal.jpg

this picture doesn't show all 3 wires going to the signal light. I can only make a good guess that the R/B wire is the parking light. I don't want to have to guess, because i don't have that much time to spend on actually working on the car.

HAILERS

R/B parking lights.

B chassis gnd

GW and GB turn signals right and left

There's no such animal as what your looking for.

There's really no need for a pinout for each plug to show what the function of each pin is.

You could just be like HAILERS and memorize the entire wiring diagram.

RETed

It's a wiring diagram, not a wiring color code.
If you know how to trace the lines on the wiring diagram, you should be easily be able to tell what circuit goes to where.

So, this means you're either too fricken' lazy to do this, or you don't know how.

I own like 12 FSM's in their original paper version, so don't tell me I don't know what the **** I'm talking about.
I troubleshoot electrical systems on these cars all the time.
I do electrical work on these cars in my sleep.
To me, electrical work is easy, but it's a PITA.
So, I would rather call you STUPID, cause I don't why it's very hard.

I don't know what you mean by "parking light" or "signal light", but I don't see a single "R/B" wire labelled anywhere on that diagram.

The turn signals are located on the bottom left hand corner of that diagram.
The diagram only shows electrical schematics for turn signals and hazards.
It shows nothing on parking lights or headlights.

HAILERS

The lack of a R/B puzzled me until I looked in the upper right hand where they show a three pin plug. Then it made sense.

R.E.wing_FC3s

do you have the individual wiring diagram supplement? section Z?? this approximates a pinout

RETed

Yes, it's a different circuit than that particular wiring diagram that's on that page.
If the OP was trying to trace that wire, he's on the wrong page.

If you're thinking that every single wire on the car is a different colour, you'd be very mistaken. That is completely impractical and unnecessary.

So what? That's the nature of electrical systems on modern(ish) cars. Each system is displayed separately because this is the most logical way to display the huge amount of info required to cover the whole car. If you want the whole electrical system on one diagram, buy a car from the 60's.

You don't have to guess, because all the info you need is there. The wiring diagrams were not written for used by electrical novices, they're for used by factory mechanics who understand electrical system and can read a wiring schematic. If you can't figure it out, you should take it to someone who can. If you don't have the time to figure it out, you should take it to someone who does. But really, it's not that hard. You shouldn't be trying to do it in a hurry, that's how mistakes happen. Just spend some time following the circuits and seeing how things are interrelated. This will make current and future jobs much easier.

Hailers hasn't done that. Like me, he's simply gotten familiar with the way the wiring diagrams are organised and figured out how to find what he's looking for quickly. Of course some question get asked and answered over and over and over, some some stuff is bound to stick...

I guess I should of put a on the end of my post. Then again, considering I was talking about HAILERS, I should of put a [humor].

Ummm. Green wire with Black stripe. Easy pickings.

******** I was talking about HAILERS, I should of put a [humor*********8

I done did knowed what you was a talking about. humor

Some are run across sooooo many times .........like green/black wire in a single connector, brown/red wire for the boost sensor output, brown/white which is almost always ref voltage for/from the ECU, green/white for the water thermo sensor, blue/black for the start signal at the ECU, black/yellow for the power to the coils and injector power, black/white for power to the solenoids, light green/black and light green/red and light green/white and just light green for the injectors at the ECU and the list goes on and on and on and on and on. Like the blue/white and blue/red for the wipers that put a gnd on the wiper motor to make it go back and forth. One for the high speed and one for the low speed and the list travels on and on and on. Like the brown/black on a series four 86/87 that is almost always the gnd circuit for the sensors in the engine bay that are all spliced together in the EM harness and teminate at pin 2A of the ECU on a series four, and then there's always that blue/yellow wire that is the tach signal from the trail coils and goe to the ECU large plug. Stuff like that sticks after a while.

And while I'm here, I've looked at a few too many aircraft wiring diagrams/schematics, and never ever run across one yet that gave even a hint as to what each pin in a plug does in life. You just follow the wire from point to point and it's fairly obvious what they do for a living. In some cases they aren't going where they're supposed to go. Not good. Somone done did goof up. Something like that.

I can tell you what each wire in X-15 and X-16 (mating plugs b/t the EM and the Front harness) do because I wasted a good deal of time looking/tracing them out (wrote it down on a piece of paper). Helps if you mating a Turbo EM harness with a non turbo Front harness.

Some people have actually asked me if I've memorised the FSM. They seem to have missed the fact that most of us access both the forum and the FSM from the same place...
