This works for vw golf 1.9 1z engined model yrs 1994/1995 with 68 pin ecu's
 
This enables you to remove the instrument cluster and still keep the immobiliser and electronic pump.
 
You will need the black box immobiliser, original key, ignition key transponder reader and the ecu from the same car.
 
How to wire the Black box immobiliser.

2  connectors

one is three pin the other is 6 pin. The 3 pin goes to the transponder reader.

The 6 pin connector is numbered if you look at the end of it. 1 to 6

So starting with pin 1

1= Black , connect this to a switched 12v i.e ignition

2 = Grey/ White, goes to the ecu

3 = Grey,  goes to  Diagnostic plug, but changes to a grey and white at the diagnostic plug end.

4 = Brown, Earth

5 = Not connected

6 = Brown, earth
 
Pin 1 was connected to the golf instrument cluster and got it's 12v feed from there.
If you removed the cluster( no 12v to pin 1) it would start for 3 seconds then stop.
 
If you use this information and it works for you please add what year and model of car you used.
 
This conversion is time consuming especially on the wiring side, so i would recommend you pay someone else to do it. when you work out how many hours it takes to do it, you soon realise it's worth the money.But if you are prepared for do it your self this info will help you get past the last stage. i.e getting it started for the first time.Big smile
 
This may work for vento's jettas etc, with a 1.9 1z tdi engine with 68 pin ecu's.
 
If you know how to get other vw tdi engines working electronically without instrument clusters etc that would be good info to add to this thread.
 
We all need help when doing conversions so it's only fair to put something back into the knowledge pool.
 
Anyway good luck and lets us know if it works for you.

The grey wire (pin 2) on the connector goes to the ecu.

Just makes me wonder if you can use the ECU's from these early ones on later systems, would have to check pin data.

Have to say in my case it is the immobiliser that I could do with getting rid of don't need it on a boat lol
Also the fly by wire throttle is some thing I could do with out if there was a way round it wires and salt water don't seem to mix well.
Still I pick the car up this afternoon so will see what has to be done hope I can mate it up to the leg.
 
I have to say 10 out of 10 to this site I have spent day's looking at the web for info on Ford engines with out much luckWacko I came to this site found all I wanted to know in 10 min's and you all seem to be very helpful keep it up it is good to see some one doing it rightThumbs Up

Hi well got the car engine out it is a M reg no immobiliser thank god . What a baby Turbo what does it boost to ?
 
But have a few problems to get over you might be able to help me with.
1st is the starter comes in from the gearbox do VW do a starter and flywheel for this engine that come's in from the engine ?
2nd slight oil leak from rear crank oil seal ? Does this mean the main's are on there way or is this common?
3rd does any one make adapter plates to fit Ford gear box or OMC leg ?
Sorry if this is off topic but you guy's seem to know all the in's and out's

My diagnosic plug was near the gearstick in the plastic house stuff.
Some are in the front dash area.
 
Suspect an adapter plate will be required to fit to a ford gearbox.

Some one did say it would be by the ash tray but nothing there did not have any wires go around the gearstiock. I have one plug that was by the servo under the bonet 6 pin but it does not fit my code read/writer ?
I have had to make adapter plate to fit OMC bell houseing also had to put ring gear on the other side of flywheel to run a starter coming in from engine side rather than gear box mounting

well yes this is true but when you look around all engines have some electrics most have ecu's .
Had to laugh fly by wire and they have a cable doing it lol

Bin the fly by wire pump. Fit a mechanical pump = no problem with electrics
The only electrics needed is a wire to the solenoid and alternator.
No ecu messing around with.
Produces good 30-40 mpg

that pump is used for the Transporter non turbo I think I don't think it would work on TDI

Looked into the mechanical pump they do do one for the turbo tdi but have to get adapter plate to fit it. Plus with the ECU pump you have more scope to get more power out of the engine by remaping. On a good note I have the engine running on the workshop floor thanks to this posting the wireing is not that much of a problem to sort and have lot's of dry room on the boat

I dont think so,  will have a look and confirm, has been a while since i looked at it.
The ecu may use the crank sensor for the golf tacho instead of the alternator.
Which might explain why it works without the alternator connected.

Has any one had a problem reprograming the ECU after bypassing clocks ?
I am logging into the ECU and it gives me the ECU info then tell me to pull fuse 12 and turn back on ? but then it just keeps repeating ???

Its as important as vagcom. Without communication you'll eventually be stuffed!
It is only 3 wires though, and only one of those goes to the ecu I think, so easy enough to fit one, particularly if your loom isn't fitted yet??

Hi it is a oblong black the wires on mine when I did the boat.  it had a brown =earth red/yellow dig + grey/white = data/ecu and a red =+ .
I found to use code reader or laptop to rewriite to ecu had to not have + disconected could be some lee way in this as when I took loom out of car to put in boat I cut the plug off by mistake lol

Also on the ross tech site it shows you where they lurk on some vw models, ie behind a blank on dash near steering wheel or down near the handbrake.

Quite a nice touch I thought  about doing would be to have the vagcom lead conncted to the OBD plug permanently and run it in tidy so you just have a small usb socket showing wherever you want it to be in the van, a bit like the obd locations on factory vws.

But I couldn't be arsed Big smile

hi everyone just got a audi 1.9 tdi ahu 1997 p reg starting without clocks and hear is how i found it.
immobiliser unit box is white not black i have no pin numbers but wire's are two that go to the key reader are in there own plastic cover and the others are as follows


1--green and black go to ecu pin number 61
2--black is ignition fed
3-- green and red diagnostic socket
4-- red and black go to the clocks

red and black goes to yellow connector of clocks and the other connector is blue and the same colour wire on the blue connector need to put these together the wire keeps going to little bulb and then from the bulb the colour changes to green and brown then that wire goes to the engine ecu and the pin number is 48 hope this helps it worked for me it must be a signal wire as it goes up and down between 0.8v to 2.3v hope this helps some one as i used this post to help me along  i know its a bit different but it might help some one Big smile

No, the key has a little chip in it, and the transducer on the steering coloumn reads the chip.
You should be able to get a new key easily enough if you have the cars documents.

I lost the key from my tdi conversion car, but found a local guy who managed to create a new chip from the immobiliser black box which he pluged into his lap top and got out the chip info.

So it can be done. My van now starts and runs using this new chip.

Apparently the key from Vw is expensive.
I was gonna offer the engine up for sale on here, But if I'm not able to get it running then I guess I'll break it up on e-bay.

Pritty sure VW do it the same way but charge a few quid for the service and wont do it if you have no documents proving the vehicle is yours etc.
 
Where did your chap get the chip from ?
Had a look at my chip a while ago and dont remember seeing any contact pins, how did he program it with his laptop.

There are immobilizer emulators out there, costing about 50£ off the Interweb. Sounds like it is worth a shot? Then you don't need the immo box, nor the coded key, it simply works like any standalone ECU would.

As I have had a T3 stolen in the past, I think it is well worth keeping the immobiliser. You also only need to look on the stolen van pages to see how much of a target our vans are these days.

I did not watch the guy create the chip for my key, I just let him get on and do his job.

I gave him the black box which he took into his van. 5>10 minutes later he came back with a cut key with a chip fitted to it.

I guess that he has a device to hold the chip while it is being programmed.

I think it cost £100 for the key and chip

The guy is called Andy Morgan tel 07899043902

He may be able to come out to you at Radstock, if not drop your immobiliser box over to me and I'll get him to do it here. Don't forget to bring your van key for him to copy.

When I try to read info from ECU gives me number's of ECU but then tells me to pull fuse 11 and turn back on .That's as far as it goes it will net read the ECU it has got to point it is driving me nut's ant idea's any one ??

Hello guys, I need some info because the Immo drives me crazy. I made a ecu / ip upgrade, I have 2 Ecu msa 15, with immo and everything. If i respect the wiring posted above, engine starts without chips near the coil. With vcds, immo box says that start is permitted, talks to ecu and key is not recognized. No matter how I do it, it won't kill the engine. Tell me that I'm crazy when everybody wants immo off, I want immo on... :)). I really need some info because if I look in every wiring diagram, pin 61 from ECU means Immo, or Immo and OBD line. So, that means pin 2 and 3 from immo box must be joined together and then to diagnostic plug? I'm correct ? Please help me clarify this!

No matter how I tried, I still get the same error from Immo box:
00546 - Data Wiring faulty: Implausible Signal

My current wiring, pin 61 from ecu goes to Immo box, pin 3 from immo box goes to diagnostic plug. - is this correct ?

Please post if you find a solution.   Pre engine install I started the engine on the floor and it needed the chip to be near the ring in order to remain running.   After install I put all the immo stuff in a sealed box in the engine bay.    A few months later I thought i''d like an immobiliser and extended all the wires to the front. Went to start it and it started fine. I was quite relieved it still started except!!! The immo chip was no ware near the ring.   In fact I could disconnect the black box and starts and runs fine.    At the time a mentioned it on here and was told lots of the original ecu never had the immo part switched on. I've assumed since that the initial apparent working of the immo with the engine on the floor was actually just air in the ip.

I dont know what to say. First time I tried 2 ECU msa 15 and with both of them car started and then stopped after 2 seconds.
After the immo wiring, it doesn't matter if I have the box plugged or not still starts.
Same here, please if you find anything let me know.
PS What is the engine check light on msa 15? all wiring diagrams says is pin 61 for us models, well that does't work, my ecu is european. 


Posted By: Scimdiesel
Date Posted: 28 Oct 16 at 14:26
Sounds exactly like mine.  I find it hard to believe that there is a get around the immobilizer by wiring the ECu or immobiliser wrong.   I was also told which may not be true that if the voltage is to low the engine might start then cut out again like if the immobilizer is activated.  In normal use the alternator would cut in and boost the voltage but when I started mine on the floor the engine had no belts on it.      

There is no engine check light on he European models.  The Glow plug light flashes angry if there is something worth being angry about.   

Maybe one day I will try a spare ECU, black box and chip and see what happens.
