I've looked for hours and can't find this info. I'm trying to figure out on a 2005 chevy silverado with bose speakers which color wires go to the rear speakers. Everything I find says blue/light blue but I don't think that holds true for the 2005 with bose.

I pulled pins out of the head unit connector in pairs to test output and this is what I come up with:

LR = Brown & GREEN / WHITE wires

RR = Black & Blue wires

I still need to know which is positive and which is negative. Any help?

I pulled pins out of the head unit connector in pairs to test output and this is what I come up with:

LR = Brown & Green w/white stripe wires

RR = Black & Blue wires

I still need to know which is positive and which is negative. Any help?

must go to the factory amp which is usually under the center console...that is where u will find your spk wire colors.....light color in front and darks in back are the positive

What exactly are you trying to do? You may experience some problems if your vehicle has onstar

Do it right the first time

Go by pin location instead of wire colors

pins A10 and A11 are right rear
pins B10 and B11 are left rear

If you look at the factory 24 pin connector you will see that the pins are actually labeled.

Sorry,

A10 and B10 are negatives.

I originally tried connecting an RCA adapter for amp to the back of the head unit, but there was almost no volume. Only after that did I figure out that the bose amp was conveniently located under the center console and the std. gm wire colors were there. I relocated the RCA adapter under the console and it works great now. The location was actually very convenient.

I haven't noticed any problems with onstar, but then again I haven't tried it after installing the adapter. I don't intend on using it anyway. Thanks for the help.

By the way, there's not much room behind the rear seat for a subwoofer posted_image
