Hi All I have got a Alpine head unit installed in my CLK, its all working fine but have a few questions, please see below: 1) Does this age of W208 have the Dimmer Illumination lead in the audio/power harness coming from the vehicle? 2) A question not of a Mercedes topic. My harness for the Alpine stereo doesn't have a illumination wire. I have a old harness sitting in the shed. Can I just pull any wire (with the soldered pins fixed on both ends) out of both block connectors and slide it into the Alpine harness? Or does the illumination wire need to have specific current/voltage ratings? The Alpine stereo does have the illumination feature but I lost my original ISO harness for the stereo hence I have an aftermarket Connects2 ISO harness that currently has no illumination lead. If the W208 doesn't have the Illumination Dimmer lead, then Q.2 can be ignored. Many thanks and appreciate any comments.
