W12 immobilizer after replacement Kessy active, cables under the steering wheel are not assigned

Hello dear community I’m new here! Have a problem with my Phaeton w12! The Kessy control unit was defective due to water intrusion!! You know the problem!! So get new device (used) let data play on it and zack it again!! Now comes but immobilizer active 1! And the steering wheel ratters while turning quite again! So here of course read everything also from the Zottel! Problem is that we have exposed the cables under the steering wheel, but unfortunately more like 3 cables have felt so 10! What still amazes us right directly on the steering wheel hanging 2 cables loose with a connection that we can’t assign!! Can someone help us what else we can do? Thank you
