Hello, I want to install tomorrow a trailer coupling on my Lupo, of course for cost reasons a ,, cheap , , ………. as well a Universal E set . the vehicle specific was simply too expensive . Lupo 1Liter , 50 Ps , ALL engine . In the guide are some symbols , where I am not sure . Right side… 1 turn signal right 2 tail light 3 Brens light 4 rear light ??? Left side ….. blue numbers 1 turn signal left 2 tail light 3 brake light 4 fog light ??? Then this is right so ?? Then continuous plus for the AFC module . According to contributions here in the forum you have to place a cable from front to rear, some write, directly from the battery …. others say somewhere from the fuse box …… If from the fuse box , then where exactly ? Now I look for the current map of the Lupo , then it can go off . Do you still have tips on what I should watch ? Greeting Munchener
