Help with line out converter on 01 tahoe

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?

You just trying to run a sub or adding amps for the highs as well?

I am running a 4 channel line out converter to a 4 channel amp. Fronts will power the components and rear will bridge for the sub.

I actually got the wiring for the 4 channel done, but now stuck on an ignition power source so the amp knows when to turn on and off.
