Hi, I bought this car as used with 1 owner. I have only aftermarket headlights installed but this is have nothing to do with the wires under steering whell as far as I know. Also I have head unit (DVD/GPS) installed. My point is when I removed the front bamper I saw factory sockets for the fog lights, then I found in this forum that this is the factory wiring and all I have to do is connect fog lights, install fog button in cabin and connect it to the wires under streeing wheel area. The way to connect it is described in pdf wiring diagram for RAV4 I found in internet but when I opened the cover I saw that there are a lot of wires with no sign to connect it as I saw in that pdf. I thought I rather get pro to connect it than do it by myself.
