Additional central locking system

Tomorrow people, it’s 0200 and I’m turning on the wheel. I’m going to install my new ZV. (because of the flipkey) Acceptance: the Omega closes/offnet switched on ground and not + switched on. Right? (Omega B of 97) -That means, the open-leitung is constantly 12V. When I press open, the voltage goes back to 0V. And the same for the closing-leitung… Right? Because after connecting, the flashers of the new ZV flash, however, does not close/open. t the old ZV I can still open and close…. The old ZV can still remain connected in parallel. Right??? Of course it would be best if someone could give me the appropriate cable colorings for closing and opening! Hope that someone can help me further… Greeting derhektor
