I wonder if someone will be able to help me , Ive done a 1.9 engine conversion and im  using a EDC15P ecu from a 2005 fabia vrs and rewiring into my car, im down to the last few ecu pins if somebody could please help me with ecu pins 11 , 14 . 15 , 18 , 21 , 22 as i need to know what they are wired too., ie  fuse box , switched lives , switched earths  ect 

many thanks in advance like 

Was that an ASZ engine code vRS?

If so:

11 - brown/blue wire to radiator fan thermal switch F18 (cars with A/C only)

14 - white wire to T11b (red 11-way conn 'K') pin 6 at firewall, cruise control

15 - grey/yellow wire to same firewall conn pin 9, related to PTC cabin heater (if fitted)

18 - blue/yellow wire to same firewall conn pin 4, going to ECU relay coil, position 15 on relay panel

21 - green/black wire to same firewall conn pin 1, going to low heat PTC relay coil (if fitted)

22 - black/grey wire to same firewall conn pin 8, going to high heat PTC relay coil (if fitted)

 

That killed some time. Need my porridge now.

Its actually for an ARL but acquired some of the  ASZ loom and ECU from a fabia vrs , had several connectors cut off but fathomed out most , just these pins and a intank lift pump left to instal and make the loom for and ile hopefully be finished with the wiring. 

 

Thanks for finding those , colours seem to match mine so thankyou , very much appreciated 

Wait, so it's not going in a Fabia, but an Audi A2?

I don't have any wiring info about Audis, so it may all be different.

Does the car have A/C, cruise control and PTC cabin heater?

Yes a heavily  modified A2 , running Cupra R brakes and uprated suspension all round , the fabia VRS six speed , engines also highly modified fully ported , high lift long duration cam , seat cup front mount and gtb1756vk so will be fun when finished 🤪

 

ive full wiring diagram for my original tdi 90 , it did have cruise but wiring is not the same has several wires to ecu compared to just one  in the fabia , I’ve left AC intact for now as unsure if the weight loss is needed , my car does have a additional heater but not the same as the fabia so unsure if there compatible or even if my original ecu  had any connections to it without reading through my current flow diagrams  and was considering retrofitting a webasto from an earlier model A2 to help winter morning warm ups but on the ta do list for final decision.
