Hello sorry for the dumb question, but I can not shut off my z150bh, what should I do, thank you.
If you mean it doesn't shut off when you remove your key, I would fire whoever installed it. Then disconnect your battery. Then wire the red and yellow wires correctly as in the installation manual. Yellow goes to a always hot +12V. Red goes to a switched (when the key is on) 12v source.
thank you, it took me back to the installer and he fixed
