sure theres more, but I can't remember them.
Well this is neat. I know i have a vacuum leak somewhere, my motor wont hold idle at all. My crank case vent is just about 4 inches of metal tubing that points straight down, where do i route this or is it supposed to be like that? Where else can i look for vacuum leaks? Everything on the valve cover/ Intake manifold seems air tight. Im running a mk3/mk4 intake manifold setup.
My fuel pump was running fine off the key (relay clicked, wiring is fine, no need to jump.) Now my pump seems dead in the water. I pulled it and tested using 2 wires right off the battery posts, pump works fine, wiring/connecters are not dirty/corroded. ECU has power (as far as i know) I'm using the proper mk3 jumper and getting spark.
98 OBD2 ABA going into 92 GTI CE2, no A/C.
I have the 4 white plugs, the yellow plug, and the brown ground. Is there anything else I need to keep on the wiring harness? I want to open it up and take out everything I don't need. I also see a couple groups of wires with relays on the end. I'm assuming I keep those too? Also another wire with plug for the Alarm/Clutch?
I'm keeping the mk2 headlight harness so I just need to know what I have to keep in the OBD2 harness and what I can get rid of. I plan on running the mk3 fan wiring too but remember the no A/C.
*edit: I'm using mk2 battery cables, too.

Third post in a row in this thread...
Car has power but won't crank. I'm pretty sure I have every plug jumped properly but I may have missed one. I'm thinking if it isn't a missed jumped plug then it's my ECU. Does this sound possible?
So the car runs!! It doesn't start though When I flip the key the starter doesn't even click. It just drains the voltage and then it goes back up when I let off the key. The starter power is hooked up to (+) terminal on battery. Another power runs from the same post on starter to the alternator. Terminal 50 plug is connected, exciter wire is connected. This is how the harness was set up when I got it.
Also, fans aren't coming on. Mk2 harness for thermoswitch with the Mk3 plug and Mk3 sensor. Mk3 fan plug wiring.
I know there is a lot of info out there for this swap but i have a few questions that i cannot find,
this is an obd2 aba ce2 swap and i am using a 97 engine bay wiring harness...
1)what color wire is connected to z1 currently i have this powered by a jump from switched power
it gives me power to the pump and fuel to the rail when power is switched on but i thought it was supposed to also power the fuel injectors
2) do i plug something into y4 for motronic pin 19
3) i do get spark when i am cranking it and can feel fuel on the return line but engine will not start when cranked
4)how do i know if the computer is getting power properly (without wiring in my obd2 diagnostic port, i just need to move the car then ill wire it in
5) can anyone send a picture of there ce2 box wired up properly for this because pictures are worth a million words
This link may help also a bit: http://www.a2resource.com/electrical/CE2.html

I am only using the engine bay wiring harness from a 97 jetta. Shotgunfacelift can you tell me what three wires you have hooked into the "Y" row... at the moment i only have a power going to y3. Also is your car running now... if so a picture of the rear of your fusebox would be awesome.
wow i am suprised at how active this thread is i mean i know it was started forever ago but there are still people out there trying to do this swap for the first time... i now have the car running with just a few things i need to fix such as the car still runs even when i shut it off... i think something is wired wrong...and alternator doesnt charge the battery right now.... but the big QUESTION is if there is anyone out there that reads this post and wants to help...??????anyone?????

Read this if you havent already.
All the info you need is in this thead
Relay Position #3 is the Digi ECU relay and it has to be pulled for the car to start (assuming you are doing this right and using the ABA Motronic ECU).
Go here (www.a2resource.com), should reveal all the mysteries, and get yourself a Bentley for both cars.
Ok, Yeah, no.
See the red jumper wire on the fuse box? The two positions that it is plugged into need 12V power. See the big red wire that is currently plugged into Y4? That wire should plug into position 30. The power from that wire needs to distributed between position 30 and 30B. You can do that with a jumper connector that comes on MkIIIs, or by splicing the big red ABA power wire with half of the MkII jumper wire and plugging those two connectors into 30 and 30B. That is what is powering your fuel pump, hence why you have no power to your fuel pump.
The fuse box positions I am referencing can be found here: http://www.a2resource.com/electrical/CE2.html
The relay in position #3 (109 in your picture) needs to be removed. That is for DigiII and will cause problems with your swap.
The black/yellow wire with a yellow connector needs to see 12v power. Preferably switched power, but running it off one of the Y posts on the fuse box will work as well.
The gray/white wire with the brown connector is your OBDII port signal. If you have an OBD connector I can help you wire that up so you can scan for codes (there are also MANY threads related to this), but it isn't required for the car to run.
The blue/white wire with a blue connector isn't needed.
The cut wires used to be in harnesses and I don't remember which colors go where, they may not be needed but a Bentley or A2Resource will give you the information you need as to what they are.
Take your time and double check ALL your connectors. If this is how you inherited the car... you've got some work to do. The PO had no idea what the hell they were doing.
