after I have finally successfully installed my radio remote control, there is only a tiny problem! When I press on it, it goes up and around

I also tried to switch the two cables that go to the ZV control line (which was interrupted), but then nothing more goes on....
Is there any two control loads for the ZV in the V8?! Or what else could be the reason for this?
I'm grateful for all the tips...
