Yeah I know what you mean. The AUE engine has 4 'teeth' on the cam trigger wheel, which is known as 'quick start'. It means the engine start on any cylinder. The 12V needs to sync to TDC on cyl 1 before it can fire, which is a bit inefficient. All part of EU emissions bollards. Anyway, said trigger is the left one. The 12V ECU won't understand the signal from it. It's more used to a single tooth as seen on the right sprocket. Maybe you can modify the right sprocket to take a 12V magnet disc under the bolt? You will also need to machine a hole into the 24V side casing and space it correctly. About 1mm should do it. The torque starts winding off at 4500rpm ish IIRC. Buy yourself a power probe! Invaluable bit of kit for this sort of thing. I'm not sure a complete Corrado wiring diagram exists anywhere other than the official ELSA books / PDFs, but KipVR on here might know. He did all the wiring himself. Yep, I do. I ran my Audi 3.2 engine with a DTA S80 and one of their DBW boxes. I think the K6 has DBW built in, which is dead handy. I would not waste your time and money on a custom loom. You will not get better quality than the original loom and you know it's reliable because it worked in the donor car for years. All you need to do is cut off the VAG plugs and connect the wires to the Emerald plugs. Then it's just simply a case of finding a suitable switched live and earth and the rest of the wiring is all Corrado, which I would not rip out personally, again, because it's worked for years. Don't fix what isn't broken ;) To figure out what wire went where, I just had the DTA ECU pin wiring diagram in front of me and I end-to-end tested the stock loom to figure out the wires. It's pretty easy, you just follow the colours back to the plug, cut em off, stick the Emerald pins on them and slot them into the Emerald's plug housing. I ran mine with full intake VVT (exhaust not worth it), stock coils, DBW, intake flap, the lot and it ran really well. None of the annoying ARMD torque management maps that VAG use. Just pulled hard everywhere with zero flat spots. Good luck! It's not hard, just take your time and be methodical and you'll be fine. This is the end result. Standalone bolted into the OEM location (using 12V ECU cradle) and OEM 3.2 loom terminated with standalone plugs. It doesn't get any simpler or neater than that ;)

T6 - brown 6 pin connector 1 - G1/10 - G1/10 - Ignition live or ECU relay power, see notes below! 2 - G1/3 - G1/3 - Fuel pump relay earth trigger 3 - bin - - Use original wires for starter motor 4 - G2/9 - G2/9 - Permanent live to ECU 5 - G1/8 - G1/8 - Fuel pump live for lamda heater, MAF, carbon canister etc 6 - G1/8 - G1/8 - Fuel pump live, but normally this pin is unused anyway T10 - orange 10 pin connector 1 - to vag-com port - Diagnostics K line 2 - bin - - MPG signal 3 - G1/3 - !!!! - Fuel pump relay earth trigger 4 - - - 5 - - - 6 - W1 - W1 - from radio/dash plug W/1 Speed signal output from dash, need to have a GTI cluster or speed sender 7 - - - Aircon 8 - - - Aircon 9 - G1/12 - ! - Need rev counter adaptor for MK1/2 cluster, MSD 8920 works well 10- - - Use original wires for reverse switch T10w - white connector 1 - - - to vag-com port on AGU ecu. I have information that you put 12v to this wire when you want to flash the ECU but thats all the information I have currently! 2 - vag-com port -as is - CAN-BUS not needed for DBC ecu but wire it for DBW 3 - vag-com port - as is - CAN-BUS not needed for DBC ecu but wire it for DBW 4 - clutch pedal switch - - 5 - - - alternator pin DFM Only used on some models 7 - - - 8 - - - EPC fault lamp 9 - - - Crash signal 10- - - Emmissions fault lamp T10e - black 10 pin connector 1 - - - cruise control switch 2 - - - cruise control switch 3 - - - cruise control switch 4 - - - brake light switch Not sure if you need this or not i leave the wire spare behind fusebox just in case 5 - - - cruise control brake switch Not sure if you need this or not i leave the wire spare behind fusebox just in case 6 - - - 7 - - - 8 - - - 9 - - - cruise control switch 10- - - T14a - 14-pin black connector 1 - G2/10 or G2/11 - !!! - Oil pressure switch, see notes below 2 - bin or direct to clocks G2/4 - !!!! - Ignition live feed for speed sender, unused unless you have electronic speedometer 3 - bin or direct to clocks G1/11 - !!!! - Signal from speed sender, unused unless you have electronic speedometer 4 - G2/3 - !!! - Coolant sender for dash 5 - Z/1 - z1 - Fuel pump live for injectors 6 - Z/1 - z1 - Fuel pump live for other sensors on engine 7 - earth to battery - - Coilpack earth 8 - Z/1 - Z1 - E/14 (via male spade) Fuel pump live for injectors (5/6 cylinder engines) 9 - earth to battery or head - G1/5 -Earth for dash temp sender 10 - bin or direct to G1/11 - !!! - Signal from speed sender, unused unless you have electronic speedometer CLOCKS ^^^^or - - ! - X-over live, so only live with ignition NOT cranking, only on some diesels 11 - - ! - Oil level/temp sensor ignition live feed 12 - - ! - Oil level/temp sensor to dash (only works MK4 cluster) 13 - fan control unit or fan after-run relay Power feed for electric coolant pump, only on 5/6 cylinder engines. so thats how mine is wired up as i write this and doesnt fire so just looking at this i think i need to read threads right first time haha o and it might be good to have a write up from the VR6 to 24V side if this a little over whelming so G1 white connector 1 - 2 - 3 - T6 brown connector/2 + T10 orange connector/3 4 - 5 - T14a/9 (14 pin black connector) 6 - 7 - 8 - T6 brown/5 + T6 brown/6 9 - 10 - T6 brown/1 11 - 12 - T10 orange/9 G2 white connector 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - T6 brown/4 10 - 11 - 12 - Z1 power - T14a/5 + T14a/6 earth - T14a/9 well hope this helps people help me haha any clues in the right direction would be much appreciated cheers John
