Which type of harness do I need to install a stereo on my 06 Chevy Silverado?

[Weezy F. Baby]

I have a 2006 Chevrolet Silverado 1500 LT w/o the Bose system and I have 2 options to choose from:

or

http://www.amazon.com/GMOS-04-OnStar%C2%AE-Interface-Amplified-Systems/dp/B000980HC4/ref=pd_cp_e_2

I do not know which harness will work on my truck. Any help will be appreciated.

The first one looks like the right one for you as it is for non-amplified non-Bose systems.
