I'm looking for the security and remote start wiring. Also, I would like to know if the 2014 version of the vehicle has the same wiring as well.
Thank You

I am confused which wire is the positive and negative.
2015 Silverado non touch screen radio.
Left Front Speaker (+/-) blue - BROWN / blue +,- radio, green 16 pin plug, pins 1 - 9
Right Front Speaker (+/-) yellow - yellow/black +,- radio, green 16 pin plug, pins 2 - 10
What I understand in here is Blue negative and Brown Blue Positive
but something do not make sense.
Other pages:
Left front
(+) dark blue
(-) brown with dark blue stripe
Right front
(+) yellow
(-) yellow with black stripe

2014 Silverado without Bose:
ITEM WIRE COLOR LOCATION
Left Front Speaker (+/-) // blue - BROWN / blue // radio, green 16 pin plug, pins 1 - 9
Right Front Speaker (+/-) // yellow - yellow/black // radio, green 16 pin plug, pins 2 - 10

Right Front + : Yellow/Black
Right Front - : Yellow
Left Front + : BROWN / Blue
Left Front - : Blue

Left Front Speaker Wire (+) Positive: Blue
Left Front Speaker Wire (-) Negative: BROWN / Blue
Right Front Speaker Wire (+) Positive: Yellow

If in doubt, you can "pop" the speakers with a small AA/AAA battery to test polarity.

If you scroll down to the paragraph that starts with "Sixth", it'll tell you how to do this.
