wow im retarded i jumped the seatbelt harness and it runs. thank you so much guys
So I'm doing obd2 were do all the stupid single wire conetioncs go that don't to into the fuse box or do I need them ( 92 gti ) ? Also is it better to swap in the headlight harness aswel. Is the car not going to start because not havung a seat belt harness or a clutch pedal harness
ok i need help with these plugs, only ones left took care of seat belt inter lock, is it only in drivers door?, took care of everything else but these, also how do i jump D8 to E2 when tere arent any plugs in them?
help me please
both of these want the same port, the mk3 is on the left and mk2 has the think red wires in it, they go to the rad
were do these two wires on my finger go (there cut) its in L , there is a wire same color on a relay with a 53 on it (stock mk2) that has think red wires that go to the plug in picture a
comes off L ,mk2
comes off J mk2
mk3 harness what is this for were does the little black wire go and the red/yellow
what is this mk3 harness
mk3 cluster harness were do these go
for your tach, you need to run a wire from the coil's negative terminal. Its under that little plastic cap. Its the lower one. You run it to the tach's pin on the fusebox. I don't remember which one it is.
Now I have a question. When using the new style coil, how do you attach the wire? These is no studs and nuts like the old coil. I thought about soldering a piece of wire with a connector on the terminal and connecting the wire to that.
It gets hot here sometimes, and I like AC. And out of all you douches, not one has shown an AC install. In this saying, SHOW ME ONE! I for one will be doing an AC/ Power steering install.
SHOW ME ONE.

any ideas on these? trying to get the last bit buttoned up.
79 scirocco w/ full ce2 swap (original switches, cluster, etc spliced in)
97 aba obd2
below are guesses..
thanks in advance
1 - white plug, 1 wire brown/red - to rear wiring harness - trunk light switch? (not used)
2 - yellow plug, 1 wire yellow/blue - to rear wiring harness - DRL
3 - black plug, 1 wire brown/yellow - to rear wiring harness - park brake
4 - red plug, 2 wires brown/yellow, blue/yellow - to rear wiring harness - DRL
5 - brown plug - ground - what does this connect to? - to fan/radio harness
1 - fuse holder in wiper harness, to S1
2 - yellow plug, 1 wire black/yellow - to engine harness (wrapped with blue/white) - fan module (not used)
3 - yellow plug, 1 wire yellow green - to rear harness
4 - black plug, 1 wire black - to E2
5 - blue plug, 1 wire blue/white - to engine harness (wrapped with black/yellow) - a/c switch (not used)
and there was another one i missed
6 - white plug, 1 wire brown/yellow - to rear harness - ??

I am in the same boat here. I have a 94 ABA into a MK1 Jetta. We have power coming into the box, but no power going to the ECU. I am using the 2-fuse box trick, so maybe I missed something? I have the #1 and #3 relays plugged in, that's all I need for the ECU and Fuel pump right? I have F G1 and G2 plugged in tight. I can hear the fuel pump prime, but no spark. I traced that back to no power to the coil, then I traced that to no power to the ECU. Then back to the fuse box, I have no power coming out. Any help would be great. Thanks.
Forgot to mention that I do have the starter lock-out jumped with a fuse. It cranks, but gets no spark for the fuel.
ok so i been driving my mk2 with the aba swap for a little while but i still have some issues. one some times she runs pretty rough at idle and i know it has to do something with the way i hooked the vacume lines up. can i get some detailed pics of the way some of you guys routed yours.
the second thing is if im coasting down the road and lightly put my foot on the gas she miss fires not real bad but i can hear it though my obnoxious exhaust... is it cause i dont have enough back pressure... idk but i drive her every day again and i love it
1991 Jetta Calypso Green Carat
In the past, I converted a mk1 Jetta to CE2 to run the ABA. That worked great. Long story short, beat the hell out of it and loved the swap, but the car was a rotbox. I also hated the mk2 stalks/mk3 cluster stuffed in the dash.
I am now back with a better Mk1 Jetta Coupe. West coast car with a clean, proper functioning CE1 system. I'm about 80% done with the swap now - the biggest obstacle being time and wiring. I am not interested in messing with the good CE1 system.
I know, "all the info is out there, use the search" - but it isn't. The majority of the information available now (2011) is in reference to obd 1 swaps, ce2 plug in jobs, or my least favorite... "piggybacking the CE2 fusebox". All the info that looks like it would lead somewhere is now a dead link - not even cached in google.
I am looking for info on this:
OBD2 aba spliced into CE1 fusebox.
The Brit posted a really good thread similar to what I'm looking for, but using an OBD2 engine/harness/ecu. http://forums.fourtitude.com/showthr...ABA-2.0-to-run
My questions is this: What is the minimum needed to run an OBD2 motor? Basically just looking to power up the ECU, and boot up the fuel pump, and subsequently strip down the obd2 harness to the bare minimum.
I am about 80% confident in getting this done myself, but it can't hurt to ask.

I like the reliability, fun, and economy of the straight aba swap. OBD2 runs nice and smooth. Its not too bad with a cam and chip either. add a gti trans and we are good to go. If and when I turbo the motor all I'd need is a chip and it will run mint too. That's a plus.
As far as the wiring goes - I will document what I do, try and get some real obd2 anti piggy back info out there. It will at least be useful to the CE1 folks. (German mk1, cabby, scirocco, some mk2)
49 pages of people telling you to use Terminal #1 for a tach signal and no one tells where to find Terminal #1. Bently says it's a Red/Black wire. which does nothing for a CE1 Cluster.
Route it right to your cluster tach wire
obd2 aba into an 91 jetta
i am not gettin spark. what gives?
i put a fuse in 1 plug. some places say they are 2. i only see 1.
the crank this morn for like 4 secs then died out and now gettin the same no spark.
I am now very close to running. Biggest obstacle is still simply time.
OBD2 into CE1 Mk1
Thinned out the harness and have some track 30 and 15 hookups mainly from plugs G1 and G2. Z1 as well. Using a Painless aux. fusebox to provide some fresh power sources... seems to work pretty good.
The ecu powers up, I can read codes off of it, and the throttle body makes the adaptation noise. Also, the fuel pump primes as it should in an A1 car. Using the Ce1 fuel pump relay. Off the top of my head, I connected G1/3 to e14 to trigger the fuel pump. is this right? I don't know yet, as the car cranks but doesnt start. I will have a better idea tonight when I get my hands on it again. I need to run a ground from the trans to the body and tie up some loose ends. I'm optimistic that it will start this week.
Turned out that I was powering my ecu with a switched power source that dropped off on the start cycle.
ECM requires 12v @ key on AND key start.
Now to button this little piggy up and shred some unavailable 175/50-13's
Anti "piggy back the box" swap
Anti "convert to ce2" swap
Got it running strong today.
I posted something from someone a page or 2 back, and that is more or less what I did for the wiring. Had to run a mk3 fuel pump relay. Everything else can be handled through the ce1 fusebox. Now to reassemble everything.
i swapped a aba into a mk2 gti ce2 fuse box, it plugged straight in,
i did not see any ground wires in the harness to plug onto the main ground area under the dash, and no wires that attached to the negative battery cables.
i figured maybe it didnt need it, so i jumped the two black plugs with 15 amp fuses and turned the key on and the two fuses instantly popped, any ideas?
