Plug assignment ZV control unit

Hello to each other, I hope someone can help me here. I would urgently need the plug assignment for the controller of the ZV. Which would be good, of course, if someone would know on which pin I have to give an impulse to turn off the immobilizer. Last Wednesday everything still worked, in the evening the car locked off the next morning he does not take the remote control (infrared) any more. So car no longer starts because of immobilizer. So to the FOH. Try a The old one didn’t work either. ZV still works via door locks. Then said cable to ZV control unit cuts through power disconnected after 1min again WFS still inside. After a new consultation with FOH we came to the decision that it can only be the IR receiver in the roof. I also wanted to order immediately, not available anymore! Then I read today in a forum that someone has installed an accessory radio remote control and then a I’m really desperate. I don’t want to give up my 14-year-old Omega so much Thanks in advance Greeting Ratzsing Griewel
