The big wires look like the SAI pump to me. Coil / injector power normally comes from a single pin plug with a red/purple wire but as it's from a phaeton, it's hard to say for sure.

In my case,coil power comes from that 2pin connector.And inector power comes from that 12pin connector.Theres generator,secundary water pump,SAi and etc connector.But the problem is,I dont know where these should go.TO the fusebox?Connected to the relay?I have elsa,but im dont have enough skills to read wiring diagrams so well

That's a very heavy gauge wire for coils. I only say SAI pump because my R32 has exactly those 2 colour wires in that gauge in a 2 pin plug exactly like that. Anyway, the coils and injectors are (normally) fed from a relay on the main SAI / ECU / coil / injector relay block. Do you have this relay block present? If so, trace the wires from that back to your plugs.
If not, try and scan the engine related harness pages and upload them on here and we should be able to figure it out.

Thanks anyway,but i figured out,what these wires is for.Two pin connector is power supply for iginiton coils(through fusebox relay and 2x40 fuse).And other connector had 2 wires for injector power supply.Through fusebox and 2x10a fuse.And other wires i dont need(air suspension control,electrical steering,climatronic etc).But now i have new issue.I have crankced engine with starter,but it wont work.Fuel pump works,fuel gets in fuel rail,spark is okay,fuses are okay.But injector wont open :S.

·Triple check your earth wires. Get some noid lights and check the injectors are even getting voltage.
