The electrician is just terrible, I don't know the rest. I put the central lock on - all the wiring from the old one remained (extra chips are hanging, extra wires are just cut off and wrapped where it turned out), I painted the necessary wires from it, and all the excess is hanging, white duct tape only on the connections, the harness is all disheveled. Well, the plastic couldn't be assembled... In short, I'm waiting for the heat and I'll redo it. And it cost 3000 rubles to connect 10 wires.
It is better to bypass Vitya the electrician
