    Hello. I connected the controller. Opens and closes. I also connected the directions, a separate diode for each. I can't handle connecting the hatch opening function. There is an additional output for the actuator from what. I measured I give + 12v. I want to plug in the switch in the middle of the car that opens the hatch. There are three pins. I know which pins "short-circuit the switch" but on one pin there is low voltage about 2V.
    The second option is to close the windows comfort signal is - 200mA. Is it possible to connect window shutters in this BMW? I have the driver's upholstery removed. The driver is rtx ke4 / se4

    Closing by the relay is a plus and the opening must track the actuator itself because the closed central from the switch will not be a plus. Search signals with a control not a meter.

    Could you tell me more exactly how with this relay? So I have to lead the cable to the actuator to the flap?

    You can find a signal from the module under the storage compartment, and go about the relay ?

    I found something like this here. My ms module only closing so I think about it here. This upper relay. I just don't understand why the relay is here. https://obrazki.elektroda.pl/91_1249379205.gif i.e. I know what the relay is for. Can it be connected to the driver's side panel? Are there all four windows only, do you need to connect each switch separately and secure the diode just like the directions, or is it enough for one and the windows will close?

    Window closing Your module has mass, BMW has a plus, so a relay is needed to convert this mass to a plus. You connect with closing under a closing signal.

    Hello. I will not start a new topic. I bought a Hotkey switch. I would like to connect the window shutters. You wrote: You close with a closing signal. So give a relay between brown and pink and it will work?

Topic summary

The discussion revolves around connecting the central control unit in a BMW E39 to manage the hatch opening and window closing functions. The user is attempting to connect a switch for the hatch but is facing issues with low voltage readings on one of the pins. Responses suggest using a relay to convert signals, as the BMW system operates on a positive signal while the user's module uses a negative signal. It is recommended to locate the signal from the module under the storage compartment and to connect the relay appropriately for window controls. The conversation also touches on the need for diodes for each window switch and the possibility of connecting all windows through a single relay.
