Trying to identify wiring on the stock stereo to install aftermarket. Closest I found on site was 2009 Sierra 1500. here is what Ive found
Light blue
dark blue
light green
different shade light green
tan, possibly orange
red with white stripe
I watched a members video on how to test. Do not have equipment. was hoping someone could identify before cutting the factory clips off

You can buy an adapter harness like the Metra 70-2105 that will match the wiring of your new receiver. This way you won't need to cut any plugs. The downside is this your truck doesn't have an accessory wire in the harness from the factory. That's why there's a long red wire- so you can run your own.
Even if you decide to cut the factory plugs you still need to run an accessory wire to be able to power your deck with the turn of the key.
If don't mind spending more, the Access AXADBX-2 or a similar interface will provide you with an accessory output.
My ex once told me I have a perfect face for radio.
