Hello There, the Philips LED Daytime Running Lights've built into my Porsche 928 GTS. I am impressed by the material and workmanship of these lights and the control unit. The description is to use, when one considers that it is multilingual. It must be connected only five cables: memory (Caution, do not use ignition plus), then connect a cable to measure and sidelights. The two lamp cables are not to be connected and everything works as it should be. There are all the connectors on the cables - it must be bought or changed anything. This daytime running lights, I would install again. Since it also has an approval, you need nothing else to do. Mfg. Walter
