The Bose add an amp nightmare

[Big2014Baby]

I have been fighting the Bose garbage in my 2014 GMC Yukon Denali XL for months. Please, if you are going to say THIS has been discussed, provide a LINK TO WHERE or respectfully shut your yap. My quest has boiled down to this question. Which is positive and negative? Green Red / White Green Stripe White Red Stripe? Which? I don have an altimeter, a potato, a witch doctor or a multimeter. Here is the harness in question. Also for your amusement, a photograph of the rabbit hole under the cup holders in the center console. Also, dear Bose, I hate you. Maybe instead of making audio equipment you should manufacture pink yard flamingos. Thanks in advance, you GM guys are the best. -Jarin

Welcome to the Forum from NH.

However, given your introduction verbiage, I will "respectfully shut my yap".

Have a good day.

I have been searching hard for this information, or wiring diagrams for weeks. Honestly I am about to put the thing together regardless. Just like Las Vegas baby, roulette 50/50 odds. Thank you for your comment, and any information would be most appreciated. Best wishes- Jarin

From what I can see in the wiring diagrams...

red is + and green is - ... for the tweeters..

That makes sense to me also, however, as I understand it, this particular cluster of wires are the "Pre-Amp" signal, so I have heard, feeding directly from the head unit aka stereo to the Bose GM factory amplifier. Work of genius that it is. I was told by some DEFINITELY competent youtubers that by tapping into the...um...white green red "stripey" part I could draw a low level RCA jack signal without interrupting any OEM or Bose related functions. There are several decent step by step guides on how to butcher this innocent wiring harness, but absolutely 0 information about the final connection to the amplifier's RCA input Jacks. Apparently, a whole bunch of people sell $100 magical plug-n-play harnesses, but that ain't how I roll. I have to whine on the forums and do wiring the hard way.

Thank you for that excellent manual sir. I have downloaded it. The very next moment I am in the proximity of a competent human I will beg them to interpret it for me.

What is the end goal here?
it should be noted that the bose amp in your vehicle is digital so doing anything without a module may be "tricky" at best
you could get a amp filtered line level out signal without much hassle
your RPO code list shown in the glove box is the reference you need to use for more detailed information as referenced in the pdf wiring diagram I linked

The end goal is to add this...

The end goal is to add this...because I can. Hypothetically.
