HELP!? RS2 ADU engine harness restoring/repair

[Kiku]

So im in the middle of restoring 94. RS2 and someone has properly violated the engine harness.
I have managed to repair and solder everything but brown/white "1.0" wire coming from relay "205".
I have looked the ADU/ABY diagrams and i cant find what is that relay ment for.

FYI: Out from the relay comes "0.75/0.5" green and black, they unite in aluminium braided isolated black tube and go to ECU.

Im hoping that some Hawk-Eye in the group knows what that relay is and where do i have to connect the damn wire.

Greeting from the US. I have a spare RS2 engine harness with this relay attached. So far it appears that the relay is part of the anti-theft/imobiliser system.

I plugged the number into ETKA and and have found the the original number has been superseded a of couple times.

431 951 253 D > 701 927 841 > 191 927 841.

I will see if I can figure out where the brown/white wire is attached. It follows the same path as the others from relay 205 into the larger bundle.

Greetings!
I thought that it shpuld be related to immo/anti-theft. If you find something then it would be much appreciated.
Thank you for answering!
