The chart for 90 civic stereo doesn't seem to match my factory wiring harness. There has never been a stereo in the car. All the speaker wires (and ground) match, but I am left with a WHITE/ blue, and a WHITE/ green. The chart has the the constant 12V as blue/white and switched 12V as yellow/red. I have neither of those wire colors.
Also the RED / black is labeled illumination. What exactly is that for?
Thank You

That is the chart I have been referencing, but in the car there is no blue/white (12V) or yellow/red (S12V). There is however a WHITE/ blue and a WHITE/ green that is not listed in the chart. I may have to do some experimenting?

Use a DMM if the colors do not match.
