trying to figure out which one goes where.

The wiring diagram I have gotten from three places on the internet matches the shop manual I have, but not the wires coming out of the stereo.

Radio 12v orange + radio harness
Radio Ground black - radio harness
Radio Ignition dk. green + radio harness
Radio Illumination brown + radio harness
Factory Amp Turn-on orange + radio harness
Notes: The amplifier is behind the glove box.
Power Antenna N/A
LF Speaker +/- tan - gray +,- radio harness
RF Speaker +/- lt. green - dk. green +,- radio harness
LR Speaker +/- brown - yellow +,- radio harness
RR Speaker +/- dk. blue - lt. blue +,- radio harness

The picture shows there isn't actually a yellow wire, there are actually three dark green wires (no black or white lines on them), and two light green.

Is there any other way to figure this out?
