Don't have a CD, so, can anyone point me to the right direction to locate the "combination relay" in the relay box? Also, need to know the location of the "light control unit". I'm still troubleshooting my left brake light problem of either not illuminating or illuminating and not going out completely (glows at about half the intensity). All this on my 92 300E. Thanks and I appreciate any input.
