Refurbishment of radio-remote conditions

Good evening together I got a radio remote control at Ebay^^ with which I can open and close my carThis is the good piece Works from the range really up to 100 meters, I’ve never experienced this yet^^ Today I wanted to install it. But have my problems with it. I measured my cables today by midday and found all the necessary cables at the bottom left in the footroom Availability calendar: thick red (current) black/white (blinker) black/green (blinker) white cable (ZV to) yellow cable (ZV to) available mass point (black) Everything fits to that. The remote control has a search function. Speaks the turn signals blink for 30 seconds. That works for me already wonderful. Only with the ZV I have a problem now. In the appendix the description I read that the ZV Plus is controlled. So I connect the yellow/black cable with a terminal to the yellow cable. I then connect the yellow cable to the black cable. Yellow/black is connected with yellow and yellow with black. So both cables connected with black. Then I connect grey with brown. I connect the grey cable to the red 12 V car battery cable. Grey is connected with brown and brown with red. So both cables connected with red. The problem is now, however, as soon as I plug in the control unit, the ZV goes in continuous course, up to up to up to up to… etc. I have to plug the device back into rest with it. Do you know what I might have done wrong? May I vllt. not put the 12V on continuous current? If not, where do I get 12V again? Greetings Black-Disk
