ABF wiring issues

i have just recently put an abf in my mk1. i understand i need to use the ecu for the abf dizzy. ive tried to just use the specific wires on the ecu ie: coil pin 2, crack position sensor and all earths and ignition lives. but yet to any joy. i was hoping to use the original mk1 coil and originally the tci but then going through the ecu that was redundant. I am planning on running the car on carbs so no worries for injectors and i know the ecu is a demobilised one. Also i know the coil and my mk1 wiring is fine as i drove it in the garage to change the engine. The ABF came out of a mk1 but using the whole engine loom on injection.
I also know the other alternative is a KR dizzy, ABF cap and KR ecu. know the other question is, is everyone using the kr ecu for the advance as obviously there isnt a straight feed to the dizzy for a vacuum advance?
One last thing, i understand the full benefits and downsides to both injection and carbs, also noise but which one is better. i am also aware of induction noise difference, but im just curious as to what people think.
Can anybody help me/ shed some light on what im doing wrong.
All help would be much appreciated

abf dizzy is no good for kr ecu as it only has 1 trigger window and is not adjustible

Dude…. Got the dizzy and the wiring I needed with ecu and everything. Fitted the dizzy and got the old girl runny nice on the old wiring. Set about changing it yesterday. Followed your instructions on a previous post but I've got a couple of issues which I'm hoping your can help me with.
1. It won't run haha.
2. Blue and white wire has a female spade connector at the end with the dizzy plug but I don't know where that plugs too.
3. I had to lengthen my crank sensor wires. Now I'm using the abf sensor. Should I use the kr 1?
Cheers

2. you need to add another black collar single pin temp sensor to the side of the head, same one as the dash runs off currently
3. you dont use the abf crank sensor anymore, instead you use the kr dizzy

Ok that's fair enough.
So the crank sensor plug is now redundant?
Also would no temp sensor on the kr loom make it not spark.
Sorry just try to get my head around it
You haven't got a diagram or pictures have you.

1 - Earth to battery -ve
2 - KR ign controller plug
3 - TCI-H plug
4 - Black - KR ign controller & TCI-H ign live - terminal 15 side of coil
5 - Green - Coil trigger - terminal 1 side of coil
\- red/black - spade is for the isv control unit, the main wire is the rev counter feed
6 - Brown - Earth to cylinder head
7 - Blue/white - Temp sensor feed (use one of the 3 on the side of the head)
8 - Dizzy plug
9 - red/yellow - Fuel pump relay earth trigger
\- black/yellow - idle switch feed (12v feed with throttle shut)

The 2 red/black wires I can cut one off can't I as I'm only using it for rev counter. don't think I've got the red/yellow fuel pump trigger but again I will check but that wouldn't stop it firing either would it?
Also do I need to use the kr TCI-H unit or will the original one be ok?
Oh yea I am using carbs aswell don't know if that makes a difference.
Cheers for all the help

the fuel pump trigger is only needed if you want your ecu to run the pump, you can use a kjet pump relay without rev limiter instead. or if using a bike carb pump it just needs an ignition live so an 18 relay would do. assumign you're using the gti pin for fuel pump power that is!
any mk1 or mk2 tci unit is fine, they all work the same

I think that were I going amiss that live wire for pump is where I need. I've got a facet pump running twin carbs so I can sort that live feed then.
That could be my problem :-o
Will have see what I can to later on then and hopefully we will have a runner.
Cheers ;-)

Right ivI've just been to it. Had a look at the loom put the temp sensor on and checked all the wiring and no joy. Put the old loom back on and straight up so dizzy, leads, TCI-H and coil are all ok.
I've looked at your loom compared to mine and there are some differences. But I removed it myself from a 1.8 16valve corrado.
Here's a pin.
Correct me if I'm wrong but:
1.TCI-H
2. Ecu
3. crank sensor
4. ve-
5. To dizzy
6. temp sensor
7. cylinder head earth
8. coil
9. coil ve+
Hopefully it's obvious to you.
Cheers.

Not a clue why it's that short but I'm going to solder it all nice and tidy when it's running.
