I'm trying to install a line out converter into my factory radio and cannot find a diagram to the wiring. The ones I have found mention wire colors that are not present. I've tried contacting Chevy as well as Helm, various audio installers, mechanics, etc. with no one able to help. Needless to say, this is quite frustrating. Any and all help will be greatly appreciated.
Below are the wires to my radio.

Just noticed that is the wrong pic uploaded. Below is the correct picture. For some reason when I spliced originally into the yellow, brown, blue and light blue my A/C, locks, and child lock buttons stopped working, however the child locks would lock and unlock constantly.

There are two big plugs that go to the factory radio. The plug in this picture is one of the two, but only contains wires going to things unrelated to sound output such as the backup camera and the microphone for bluetooth/OnStar communication. I have attached wiring diagrams that should help you.
Please note that the factory radio already outputs a low level signal (referred to as "LO AUDIO" in the diagrams I've attached). All 2010+ Equinox models have a factory amplifier. Because of this, you won't need a line level (high/speaker level to low/preamp level) converter if you are connecting an aftermarket amp directly to the factory radio. You should be able to connect some RCA patch cables (RCA plug on one end and bare wire on the other) directly to the radio. Be sure to be consistent when making your connections to maintain correct signal polarity. Connect the positive side of the outputs to the tips of the RCA cables and the negative to the outer part. If polarity is inconsistent your stereo will sound bad and bass will be weak because speakers will be cancelling out the output of each other (i.e. when the woofer cone is moving inward on one speaker, but outward at the same time on another speaker).
With all that being said, the factory radio may actually output a speaker level signal if the REMOTE ENABLE SIG output is not connected to the factory amplifier. This is the case with some other GM models, but some testing and/or trial & error will need to be done to confirm this is or is not the case with this specific radio.
I don't have any RCA Patch cables, just the standard RCA that came with my amp. So maybe it would just be easier to use the LOC? if so, I'm not sure where I should put it if the wiring behind the radio isn't what I'm looking for.

Read my previous post again. You may not need the LOC at all. It serves no purpose if the factory radio is already putting out a preamp/low level signal. If you're installing an aftermarket amp, it would be wise to remove the factory amp or at least bypass/remove it.
Also, cut one end of your RCA cord off, and viola - you have patch cables.
