If today’s buddy comes to me who wants to build a parking aid at his Kangoo II Maxi , or rather a “rempelwarnanlage ” . The Holde has now already hit back left and now front right and left . He is visibly angry …. Now he arrived with a parking aid for front and rear in a system . Some Ebay , Amazon , Aliexpress scrap . To the hardware are 1 set of long cables with sensors connected to the control unit with no intermediate plug at the shock rod and 1 set of short cables with sensors on it even without intermediate plug. So drill holes, sensors in and the cables from the front completely through the whole car to the control unit. Makes sense because you never have to dismantle the front bumper …. The same only the shorter way. No matter we have still nothing built in. Now to the connection plan of the 4 cables for the power supply see picture. Mass is clear, yellow is for the back, red will be a permanent plus ( 15) and the bla ue ?? My guess would be that I should get a speed signal from ABS here like with original systems, but from the English I don’t get smart. Connect Feel Brake “+” If that’s so wondering but which one I should tap there and then I can also put a cable up to the front ….. what a scrap …. I could also build the control unit forward to shorten the cable paths, but garbage remains nevertheless.
