    Retrofi Webasto auxiliary heater to C4

    Hello fellows,

    i am able to buy a full kit from a damaged car.
    I have found a German description for the install but it is not clear
    what should i do with climate control unit. Its says i have to attach AC Relay 87 pin
    to Connector D #.. pinout.
    Since is it in German it is not clear for me,i have checked the AC wiring diagram.
    pinout #1 is data link connector.
    It is also not clear that what "Zusatzrelais" is i got additional relay for translating but i don't konw exactly which relay is that

    I have attached the file.
