Wondering were does the stereo crossover box mount to? Has 2 flanges with small slotted holes in it. Service manual looks like it mounts to left side of glove box? Not very good location if you ask me. What am I not seeing. Also have this light with yellow wire. Socket has metal tab with a blue cover. Doesn't look like it would put out enough light to say so. Thought it was the glove box light but now I am not so sure.
