Wiring HELP

[Hoppy92]

I have got my bently manual on the 26th of april and since i have been reading up and what not through out the whole book. I have a 92 cabriolet, there is nothing specific for the year 92 in this book and this brings me to a few questions.....?

what years does a 92 correspond with/match?

what is digifant II?

What years did digifant II come in?

Where can you learn about digifant II?

AND HOW THE HELL do the wiring diagrams work for the VW's, or how does Current Track Diagraming work? Maybe im just not comprehending what the bently is saying about the wiring. Im finding it quite confusing to be honest and ANY HELP what so ever would be so helpful!

Ive also printed this off at work


but this does not correspond with the Digifant connector in my car. None of the information that im getting seems to be correct to the car.
I work at VIP parts tire and service and i have access to the ALLDATA program but the info on the program doesnt seem correct.. Does anyone know why nothing is Specific to the year 92?

There was a thread recently on how to tell if it is digi 1 or two so try a search on that one.

How to read diagrams see cabby info

[Hoppy92]

well im assuming its a Digifant II because the ECU says DIGIFANT II on it?

[stronglikebull]

is your car a car that was originally sold in california? i think digifant 1 was california cars, but i could be wrong.

[Hoppy92]

i dont think it was sold in california its a wolfsburg karman edition. the VIN starts with WVW doesnt that mean where its from?

If the 5th digit in the VIN is "B" it's Digifant II, if it's "C" it's Digifant I and should have a check engine light on the dash.

[Hoppy92]

The 5th digit/letter is a B which equals DIGIFANT II. what's the 9th digit correspond with? On the Cabby info site the example had a 5 mine has a 9 what's the difference ?

check with cabby-info.com for more info on that. also there may, may, still be the original sticker on the underside of the the hood that says which digifant it has.

The VIN decoder clearly states that the 9th digit is the internal check code. Each code is specific to each individual VIN. How it's calculated: http://www.cabby-info.com/vin.htm#Check .

[riotbeast]

The first letter of the vin is were the car was
Made... W is for germany.... 3 is for
Mexico(the vw's i completly stay away from) but i beleve all the cabriolets were made in germany

[tolusina]

If you've gotten as far as the ECU plug, DigiFant II has 25 pins, DigiFant I has 38.

Easiest way I know of to explain the current track diagrams is by following a circuit while trying to diagnose a specific issue.
What issue is the car having that you are trying to diagnose?

I'm still have the same problem as my other thread. No speak while cranking.... Seems to be a mistory problem for me. I may just get a new wiring harness for the car because there are wires with the outer coating over the copper all distorated and some wires are even melted.. It's a mess!

[Hoppy92]

Here is my DIGI connector



on the other pictures i put up it says there is 13 pins on the top row and 14-25 on the bottom row mine onlyh has 12 on the top row?

[CajunSpike]

A simple answer to this digi1/digi2 question would be for you to post a photo of your ignition coil.

digi2 coils are round...digi1 are more square if I remember right.

this is a digi2 coil, in the background of this shot.


As for your pic above this post, you might have 12 actual pins, but there are 13 holes..thats what they meant.

[Hoppy92]

theres only 12 holes all together and 10 pins out of the 12 holes. and its digifant II

Do your coil wire trick, unplug the connector from the Hall generator in the base of the distributor.
Using a suitable jumper of some sort (paper clip, safety pin, whatever) connect to the center wire of the Hall generator harness, 'scratch' that center wire connector to ground, spark should happen every time ground is released.

Post your findings.

This MUST be fixed.

I got lost following all your threads, where is this melt down located in the car?

From several of the photos you've posted, your car DEFINITELY has DigiFant II, so never mind any DigiFant I specific stuff.

[CajunSpike]

The wires to the throttle body idle switch don't look in very good shape either. the plug under throttle body with two wires...looks like the insulation in bad shape.

[Hoppy92]

Blue and red wire to the throttle body idle switch is fryed in a few places and that wire goes straight to the ECU from the switch.... from what i can see from the wires comming out of the ECU the Blue and Red idle switch wire got other wires hot and screwed up more wires like the brown and green wire that goes to the blue CTS. this car is a wiring mess ive had the car for over a month and nothings been figured out and i just wanna drive the damn car!

you say that this

needs to be fixed but what should go there? there is so much stuff unver the hood that is just free floating it isnt even funny!

Bentley shows no blue/red connected to the throttle switches.
The only blue/red I see in the DigiFant schemes connects to the MAF, critical to how the car runs, irrelevant to the no spark issues.
---
Bentley shows Pin 19 at the ECU as the main ground for the ECU, says it connects to ground on the engine block, I think it means on the cylinder head coolant flange, like one of the two cut wires shown above.
---
D'oh, I just noticed in the pic above, just above the heater hose, a black? wire twist spliced together, that is unlikely to work well. Where to those wires lead?
---
I rarely advocate for harness replacement, preferring to find and fix individual issues.
Frankly, from your pics and descriptions, your car would challenge my skills to complete all such needed repairs, I might be inclined to replace the engine harnesses if I could source decent junk yard replacements.
---
Oh, and @ Cajun too, I'm getting schematically jaded. I've been spending quality time with A3 Bentley schemes, now, looking back at these A1 Cabby/'rocco Bentley schemes, I find them lacking. And, all the VW Bentley schematics really pale in comparison to what GM and Ford make available.
Finding Chilton schemes totally inadequate for my Ranger, I stepped up for an alldatadiy.com subscription for the truck. In there, I've found excellent diagrams of every connector in the vehicle with circuit numbers and wire colors which all cross reference back to the excellent schematics. This level of detail totally allowed me to fix an initially very perplexing electrical issue that came down to a previous, color blind, individual crossing two wires in a single connector. Took me two days to find, a minute to actually correct.
I'm wishing the Euro and Asian manufacturers would take clues from the lead that domestics have demonstrated.
And, sad to say, I doubt that alldatadiy.com will offer any rescue or relief for VW Nuts, alldatadiy.com info can only be as good as what the factories make available, Bentley is probably as good as it gets.

tolusina, if not for you and the rest of the vortex nuts, i might have given up on that cabrio already.

When i've done all I know how to do...i just run into a brick wall.

I just try to pass on as much help to others as have been given to me.

As for those yellow wires, they remind me of the wires that would go to the 'oil pressure can sensor' that goes in that place on the side of the head. that sensor doesn't look right for a digi car.

The part that usually goes there would be the 3rd one on this page.

http://www.germanautoparts.com/Volks...ectrical/150/1

Thats where the yellow wires would hook to. I'm betting two of the lower three gauges aren't working.

[tolusina]

.....the wires that would go to the 'oil pressure can sensor' that goes in that place on the side of the head.....

I figured to wait until his engine runs before jumping after the oil pressure gauge and warning buzzer issues.
Someone clueless has sure spent time under the hood of this car, clues about the clueless are tough to cipher.

[Hoppy92]

Well I'm not clueless but close but i havent done anything other then trace wires and checked what wires were burn and what not... I've taken the dash out and changed all the grounds under the hood and that's all I've done with the car.

So you think getting a wiring harness wouldn't be a bad idea? There's a junk yard not fr from me, "Rhein of Maine" and they have a harness for $120 which doesn't seem that bad? Does it?

Well the Bentley that I use has the difference between the models. Most of it is written for the mk1 frame, where as the specifics that are different are covered. I owned a 90, and 89, currently drive a 93, and a 92. I may have a hard time locating specific information that I need, but it is all there, ya just got to look for it.

Wiring.

Hint, the 12V+ is at the top.
The Grounds are at the bottom of the page.

Current track is the number on the bottom of the page that you are looking for.

Voltage is felt, Current flows and is what causes most stuff to illuminate, move, or spin.

www.cabbyinfo.com is a site that you should get to know.

How to read the schematics?:

I can't believe how similar my restoration is to yours. I'm reading the bentley as well and learning a lot just from learning and doing. I have a lot of chewed up wires from mice eating at them.

Are you still getting one spark?

[Hoppy92]

The wiring schematic seem quite in depth and I get the positive and negative parts on the diagrams but none of them seem to match whats in my car!? That's what's confusing me!

And yes only one spark. When the key is turned to the "on" position it sparks then it sparks once more when the engine starts to crank over but then nothing.? I can't figure out what's going on!

[briano1234]

Do you have an after market alarm? Is it Automatic?

[Hoppy92]

There was some after market wiring in the car not sure if it's alarm wires or remote start wires. There was a ground wire connected and then the was an LED light on the right had side that im assuming was a flashing alarm light

Those are the wires that came out!

The cars a standard transmission.

[Hoppy92]

Would the O2 sensor have anything to do with the spark issue? Because there is a O2 sensor at the "header" and the wires are gone out of the back of it. Would this prevent spark or just make te car run like crap because I can't read rich or lean?

Most it will cause is a slight run issue ... I have no o2 working at the moment on my swap and she runs okish but ut definetly wouldnt prevent spark

[briano1234]

Sounds as if you remove the after market wires, but still have a issue the wiring that they ran to it.

[Hoppy92]

The aftermarket wires were sliced into the cars wirning harness with something like this

But they have a connector on then for a flat connector to go into

[briano1234]

Those have been known to cut the wires they are splicing.

[Hoppy92]

It's exactly like this but idk what wires they are attached to??

[briano1234]

Them too.
When they are applied, they cut through the insulation. That Cut if you apply a too small of one to the wrong size wire can cut it.

If pig tails exists then you may be grounding out voltages.
