Hi All,
I am in the middle of various upgrades to my 2012 Suburban audio system head unit, amp and speakers. I have the Bose system (non-digital i think). I have already swapped out the head unit with a Pioneer NEX unit using a harness adapter. Works pretty well so far. But i think one of my stock speakers has blown so i am going down the rabbit hole of replacing all the stock speakers (and possibly adding an amp/sub but nor sure about that yet). Not sure if i will keep the Bose amp or try and bypass it and use a new amp. i would prefer to keep the Bose amp for ease of installation.

I cannot seem to find the CORRECT pinouts/wiring diagram for the existing BOSE system and wiring. They would save me a ton of hassle. Anyone have that or point me? I have scoured the internet and come up short every time.

Thank you!

 

alldatadiy.com has the full shop manual with all the electrical diagrams. For me it's worth the price of the subscription for all my vehicles.

 

Thank you for the link. However, adding yet another subscription plan to my life for something i just need once it is a no-go. Man everything is going to be subscription based soon!

 

If your doing your own repairs it's worth the money though. Especially the diagnostics steps. My '11 LTZ has 41 readable modules linked in the onboard communications system.

 

Could any of you actually give info instead of acting like a subscription is the only guide out there? Now days companies are trying to make it harder to upgrade your vehicles buy costing you more money for everything including guides or wiring diagrams. One of you people has dealt with this problem. So why not give out that information?.?

 

Information has always costed money

 

There are still some good free information sources through public library online. This is one I use.
The attached PDF is the entire audio system wiring diagram.
